Show all factor pairs, prime factorization (factor tree), sum of factors (divisors), aliquot sum, and prime power decomposition of 196.

We do this by listing out all pairs of numbers greater than 0 and less than or equal to 196 who have a product equal to 196:

196 = 1 x 196

196 = 2 x 98

196 = 4 x 49

196 = 7 x 28

196 = 14 x 14

There are 5 factor pairs of 196.

1, 2, 4, 7, 14, 28, 49, 98, 196

1, 7, 49

2, 4, 14, 28, 98, 196

Proper factors are all factors except for the number itself, in this case 196

1, 2, 4, 7, 14, 28, 49, 98

Now, show the prime factorization (factor tree) for 196 by expressing it as the product of ALL prime numbers.

196 = 2 x 98 <--- 2 is a prime number

Next step is to reduce 98 to the product of prime numbers:

98 = 7 x 14 <--- 7 is a prime number

Next step is to reduce 14 to the product of prime numbers:

14 = 2 x 7 <--- 2 is a prime number

Next step is to reduce 7 to the product of prime numbers:

1 + 196 + 2 + 98 + 4 + 49 + 7 + 28 + 14 =

The aliquot sum is the sum of all the factors of a number except the number itself

1 + 2 + 98 + 4 + 49 + 7 + 28 + 14 =
