Proper factors are all factors except for the number itself in this case 18
1, 2, 3, 6, 9
Prime factorization for 18
18 = 2 x 9 <--- 2 is a prime number
Reduce 9 to the product of primes:
9 = 3 x 3 <--- 3 is a prime number
Reduce 3 to the product of primes:
Show prime factorization:
2 x 3 x 3
Prime Power Decomposition
2 x 32
Show the sum of factors (divisors) for 18
1 + 18 + 2 + 9 + 3 + 6 = 39
Show the aliquot sum:
This is the sum of all the factors except the number
1 + 2 + 9 + 3 + 6 = 21
What is the Answer?
1, 2, 3, 6, 9, 18
