# Show Factorization for 36

<-- Enter Number

Show all factor pairs, prime factorization (factor tree), sum of factors (divisors), aliquot sum, and prime power decomposition of 36.

We do this by listing out all pairs of numbers greater than 0 and less than or equal to 36 who have a product equal to 36:
NumberFactor PairsFactor Pairs Sum
361 x 3637
362 x 1820
363 x 1215
364 x 913
366 x 612

There are 5 factor pairs of 36.

## List factors of 36

1, 2, 3, 4, 6, 9, 12, 18, 36

1, 3, 9

## List even factors of 36

2, 4, 6, 12, 18, 36

## Calculate proper factors of 36

Proper factors are all factors except for the number itself, in this case 36
1, 2, 3, 4, 6, 9, 12, 18

Now, show the prime factorization (factor tree) for 36 by expressing it as the product of ALL prime numbers.
36 = 2 x 18 <--- 2 is a prime number

Next step is to reduce 18 to the product of prime numbers:
18 = 3 x 6 <--- 3 is a prime number

Next step is to reduce 6 to the product of prime numbers:
6 = 2 x 3 <--- 2 is a prime number

Next step is to reduce 3 to the product of prime numbers:

2 x 2 x 3 x 3

22 x 32

## Show the sum of factors (divisors) for 36

1 + 36 + 2 + 18 + 3 + 12 + 4 + 9 + 6 = 91

## Show the aliquot sum:

The aliquot sum is the sum of all the factors of a number except the number itself
1 + 2 + 18 + 3 + 12 + 4 + 9 + 6 = 55
