Calculate proper factors of 80
Proper factors are all factors except for the number itself
in this case 80
1, 2, 4, 5, 8, 10, 16, 20, 40
Prime factorization for 80
80 = 2 x 40 <--- 2 is a prime number
Reduce 40 to the product of primes:
40 = 5 x 8 <--- 5 is a prime number
Reduce 8 to the product of primes:
8 = 2 x 4 <--- 2 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 2 x 5
Prime Power Decomposition
24 x 5
Show the sum of factors (divisors) for 80
1 + 80 + 2 + 40 + 4 + 20 + 5 + 16 + 8 + 10 = 186
Show the aliquot sum:
This is the sum of all the factors except the number
1 + 2 + 40 + 4 + 20 + 5 + 16 + 8 + 10 = 106
What is the Answer?
1, 2, 4, 5, 8, 10, 16, 20, 40, 80
