Positive or Negative Number Test:
Positive Numbers > 0
Since 100000 ≥ 0 and it is an integer
100000 is a positive number
Whole Number Test:
Positive numbers including 0
with no decimal or fractions
Since 100000 ≥ 0 and it is an integer
100000 is a whole number
Prime or Composite Test:
Since 100000 has divisors other than 1 and itself
it is a composite number
Perfect/Deficient/Abundant Test:
Calculate divisor sum D
If D = N, then it's perfect
If D > N, then it's abundant
If D < N, then it's deficient
Divisor Sum = 1 + 2 + 4 + 5 + 8 + 10 + 16 + 20 + 25 + 32 + 40 + 50 + 80 + 100 + 125 + 160 + 200 + 250 + 400 + 500 + 625 + 800 + 1000 + 1250 + 2000 + 2500 + 3125 + 4000 + 5000 + 6250 + 10000 + 12500 + 20000 + 25000 + 50000
Divisor Sum = 146078
Since our divisor sum of 146078 > 100000
100000 is an abundant number!
Odd or Even Test (Parity Function):
A number is even if it is divisible by 2
If not divisible by 2, it is odd
| 50000 = | 100000 |
| 2 |
Since 50000 is an integer, 100000 is divisible by 2
it is an even number
This can be written as A(100000) = Even
Evil or Odious Test:
Get binary expansion
If binary has even amount 1's, then it's evil
If binary has odd amount 1's, then it's odious
100000 to binary = 11000011010100000
There are 6 1's, 100000 is an evil number
Triangular Test:
Can you stack numbers in a pyramid?
Each row above has one item less than the row before it
Using a bottom row of 447 items, we cannot form a pyramid
100000 is not triangular
Triangular number:
Rectangular Test:
Is there an integer m such that n = m(m + 1)
No integer m exists such that m(m + 1) = 100000
100000 is not rectangular
Rectangular number:
Automorphic (Curious) Test:
Does n2 ends with n
1000002 = 100000 x 100000 = 10000000000
Since 10000000000 does not end with 100000
it is not automorphic (curious)
Automorphic number:
Undulating Test:
Do the digits of n alternate in the form abab
In this case, a = 1 and b = 0
In order to be undulating, Digit 1: 111111 should be equal to 1
In order to be undulating, Digit 2: 000000 should be equal to 0
Since our digit pattern does not alternate in our abab pattern100000 is not undulating
Square Test:
Is there a number m such that m2 = n?
3162 = 99856 and 3172 = 100489 which do not equal 100000
Therefore, 100000 is not a square
Cube Test:
Is there a number m such that m3 = n
463 = 97336 and 473 = 103823 ≠ 100000
Therefore, 100000 is not a cube
Palindrome Test:
Is the number read backwards equal to the number?
The number read backwards is 000001
Since 100000 <> 000001
it is not a palindrome
Palindromic Prime Test:
Is it both prime and a palindrome
From above, since 100000 is not both prime and a palindrome
it is NOT a palindromic prime
Repunit Test:
A number is repunit if every digit is equal to 1
Since there is at least one digit in 100000 ≠ 1
then it is NOT repunit
Apocalyptic Power Test:
Does 2n contain the consecutive digits 666?
2100000 = INF
Since 2100000 does not have 666
100000 is NOT an apocalyptic power
Pentagonal Test:
It satisfies the form:
| n(3n - 1) | |
| 2 |
Check values of 258 and 259
Using n = 259, we have:
| 259(3(259 - 1) | |
| 2 |
| 259(777 - 1) | |
| 2 |
100492 ← Since this does not equal 100000
this is NOT a pentagonal number
Using n = 258, we have:
| 258(3(258 - 1) | |
| 2 |
| 258(774 - 1) | |
| 2 |
99717 ← Since this does not equal 100000
this is NOT a pentagonal number
Pentagonal number:
Hexagonal Test:
Is there an integer m such that n = m(2m - 1)
No integer m exists such that m(2m - 1) = 100000
Therefore 100000 is not hexagonal
Hexagonal number:
Heptagonal Test:
Is there an integer m such that:
| m = | n(5n - 3) |
| 2 |
No integer m exists such that m(5m - 3)/2 = 100000
Therefore 100000 is not heptagonal
Heptagonal number:
Octagonal Test:
Is there an integer m such that n = m(3m - 3)
No integer m exists such that m(3m - 2) = 100000
Therefore 100000 is not octagonal
Octagonal number:
Nonagonal Test:
Is there an integer m such that:
| m = | n(7n - 5) |
| 2 |
No integer m exists such that m(7m - 5)/2 = 100000
Therefore 100000 is not nonagonal
Nonagonal number:
Tetrahedral (Pyramidal) Test:
Tetrahederal numbers satisfy the form:
| n(n + 1)(n + 2) | |
| 6 |
Check values of 83 and 84
Using n = 84, we have:
| 84(84 + 1)(84 + 2) | |
| 6 |
| 84(85)(86) | |
| 6 |
102340 ← Since this does not equal 100000
This is NOT a tetrahedral (Pyramidal) number
Using n = 83, we have:
| 83(83 + 1)(83 + 2) | |
| 6 |
| 83(84)(85) | |
| 6 |
98770 ← Since this does not equal 100000
This is NOT a tetrahedral (Pyramidal) number
Narcissistic (Plus Perfect) Test:
Is equal to the square sum of it's m-th powers of its digits
100000 is a 6 digit number, so m = 6
Square sum of digitsm = 16 + 06 + 06 + 06 + 06 + 06
Square sum of digitsm = 1 + 0 + 0 + 0 + 0 + 0
Square sum of digitsm = 1
Since 1 <> 100000
100000 is NOT narcissistic (plus perfect)
Catalan Test:
| Cn = | 2n! |
| (n + 1)!n! |
Check values of 11 and 12
Using n = 12, we have:
| C12 = | (2 x 12)! |
| 12!(12 + 1)! |
Using our factorial lesson
| C12 = | 24! |
| 12!13! |
| C12 = | 6.2044840173324E+23 |
| (479001600)(6227020800) |
| C12 = | 6.2044840173324E+23 |
| 2982752926433280000 |
C12 = 208012
Since this does not equal 100000
This is NOT a Catalan number
Using n = 11, we have:
| C11 = | (2 x 11)! |
| 11!(11 + 1)! |
Using our factorial lesson
| C11 = | 22! |
| 11!12! |
| C11 = | 1.1240007277776E+21 |
| (39916800)(479001600) |
| C11 = | 1.1240007277776E+21 |
| 19120211066880000 |
C11 = 58786
Since this does not equal 100000
This is NOT a Catalan number
