How to Calculate Factor Pairs of 80

Step-by-Step Process

To find all factor pairs of 80, we need to identify all integers that divide 80 evenly (with no remainder).

Start with the smallest factor, which is always 1
Check each integer from 1 up to the square root of 80 (v80 ≈ 8.94)
For each factor found, its corresponding pair is calculated by dividing 80 by that factor

Calculation Example

Let's work through finding the factor pairs of 80:

Factor Check	Division	Result	Factor Pair
80 ÷ 1	80.00	Integer result	(1, 80)
80 ÷ 2	40.00	Integer result	(2, 40)
80 ÷ 3	26.67	Not a divisor	-
80 ÷ 4	20.00	Integer result	(4, 20)
80 ÷ 5	16.00	Integer result	(5, 16)
80 ÷ 6	13.33	Not a divisor	-
80 ÷ 7	11.43	Not a divisor	-
80 ÷ 8	10.00	Integer result	(8, 10)

More About Abundant Numbers

Abundant Numbers

An abundant number is a positive integer for which the sum of its proper divisors is greater than the number itself. The number 80 is abundant because the sum of its proper divisors (106) exceeds 80.

The smallest abundant number is 12, whose proper divisors are 1, 2, 3, 4, and 6, which sum to 16.
