Factor Pairs of 25

A Factor Pair of number 25 is a combination of two factors which can be multiplied together to equal 25.

List of all possible Factor Pairs of 25:

  • 1 × 25 = 25
  • 5 × 5 = 25

How to find the Factors of 25

Divide 25 by every whole number from 1 up to 5. Each division without a remainder gives a factor and its pair. There is no point going further: 6 × 6 = 36 is already greater than 25, so any larger divisor would pair with a smaller one you have already checked.

  • 25 ÷ 1 = 25 — factors 1 and 25
  • 25 ÷ 2 — remainder 1, not a factor
  • 25 ÷ 3 — remainder 1, not a factor
  • 25 ÷ 4 — remainder 1, not a factor
  • 25 ÷ 5 = 5 — factor 5, paired with itself

Why 25 has exactly 3 factors

The count follows from the prime factorization: add 1 to each exponent and multiply. Counting the divisors this way needs no trial division at all, however large the number is.

25 = 52

(2 + 1) = 3

Step-by-step factorization: Prime factors of 25.
