Factor Calculator

A factor is any whole number that divides into another number evenly, meaning it leaves a remainder of zero. For example, the factors of 6 are 1, 2, 3, and 6.

Factor pairs are pairs of two integers that, when multiplied together, equal the original number. For example, the factor pairs of 12 are (1, 12), (2, 6), and (3, 4).

Yes. Every positive factor of a number has a corresponding negative factor. For example, since 2 × 5 = 10, then (-2) × (-5) = 10, meaning -2 and -5 are also factors of 10.

Divide the number systematically by every integer starting from 1 up to the square root of the number. If there is no remainder, both the divisor and the resulting quotient are factors of that number.

A prime factor is a divisor of a number that is also a prime number (it has no factors other than 1 and itself). For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, but its prime factors are only 2 and 3.
