What Are Factors?
Factors (or divisors) of a number are integers that divide it exactly, with no remainder. For example, the factors of 12 are: 1, 2, 3, 4, 6, 12.
Number Types
Perfect number: sum of proper divisors equals the number (6, 28, 496). Abundant: sum greater than the number. Deficient: sum less than the number.
Finding Factors
To find factors, divide the number by each integer from 1 to its square root. If division is exact, both the divisor and quotient are factors.
