Calculate proper factors of 72 Proper factors are all factors except for the number itself in this case 72
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36
Prime factorization for 72 72 = 2 x 36 <--- 2 is a prime number
Reduce 36 to the product of primes:
36 = 3 x 12 <--- 3 is a prime number
Reduce 12 to the product of primes:
12 = 2 x 6 <--- 2 is a prime number
Reduce 6 to the product of primes:
6 = 3 x 2 <--- 3 is a prime number
Reduce 2 to the product of primes:
Show prime factorization: 2 x 2 x 2 x 3 x 3
Prime Power Decomposition 23 x 32
Show the sum of factors (divisors) for 72 1 + 72 + 2 + 36 + 3 + 24 + 4 + 18 + 6 + 12 + 8 + 9 = 195
Show the aliquot sum: This is the sum of all the factors except the number
1 + 2 + 36 + 3 + 24 + 4 + 18 + 6 + 12 + 8 + 9 = 123
What is the Answer?
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
