Proper factors are all factors except for the number itself in this case 40
1, 2, 4, 5, 8, 10, 20
Prime factorization for 40
40 = 2 x 20 <--- 2 is a prime number
Reduce 20 to the product of primes:
20 = 5 x 4 <--- 5 is a prime number
Reduce 4 to the product of primes:
4 = 2 x 2 <--- 2 is a prime number
Reduce 2 to the product of primes:
Show prime factorization:
2 x 2 x 2 x 5
Prime Power Decomposition
23 x 5
Show the sum of factors (divisors) for 40
1 + 40 + 2 + 20 + 4 + 10 + 5 + 8 = 90
Show the aliquot sum:
This is the sum of all the factors except the number
1 + 2 + 20 + 4 + 10 + 5 + 8 = 50
What is the Answer?
1, 2, 4, 5, 8, 10, 20, 40
