Factor Pairs Table

Number	Factor Pairs	Factor Pairs Sum
78	1 x 78	79
78	2 x 39	41
78	3 x 26	29
78	6 x 13	19

There are 4 factor pairs of 78

List factors of 78

1, 2, 3, 6, 13, 26, 39, 78

List odd factors of 78

1, 3, 13, 39

List even factors of 78

Calculate proper factors of 78

Proper factors are all factors except for the number itself
in this case 78

1, 2, 3, 6, 13, 26, 39

Prime factorization for 78

78 = 2 x 39 <--- 2 is a prime number

Reduce 39 to the product of primes:

39 = 3 x 13 <--- 3 is a prime number

Reduce 13 to the product of primes:

Show prime factorization:

2 x 3 x 13

No prime power decomposition exists since
there are no duplicate prime numbers in the prime factorization:

Show the sum of factors (divisors) for 78

1 + 78 + 2 + 39 + 3 + 26 + 6 + 13 = 168

Show the aliquot sum:

This is the sum of all the factors except the number

1 + 2 + 39 + 3 + 26 + 6 + 13 = 90

What is the Answer?

1, 2, 3, 6, 13, 26, 39, 78

What 7 concepts are covered in the Factorization Calculator?

aliquot sum: aliquot sum is the sum of all the factors of a number except the number itself
digit: Any of the numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) used to construct a number
factor: a divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n.
factorization
power: how many times to use the number in a multiplication
prime number: a natural number greater than 1 that is not a product of two smaller natural numbers.
sum: the total amount resulting from the addition of two or more numbers, amounts, or items
