(number 122 has 4 factors)

Factor Pairs of 122

A Factor Pair of number 122 is a combination of two factors which can be multiplied together to equal 122.

List of all possible Factor Pairs of 122:

  • 1 × 122 = 122
  • 2 × 61 = 122

How to find the Factors of 122

Divide 122 by every whole number from 1 up to 11. Each division without a remainder gives a factor and its pair. There is no point going further: 12 × 12 = 144 is already greater than 122, so any larger divisor would pair with a smaller one you have already checked.

  • 122 ÷ 1 = 122 — factors 1 and 122
  • 122 ÷ 2 = 61 — factors 2 and 61
  • 122 ÷ 3 — remainder 2, not a factor
  • 122 ÷ 4 — remainder 2, not a factor
  • 122 ÷ 5 — remainder 2, not a factor
  • 122 ÷ 6 — remainder 2, not a factor
  • 122 ÷ 7 — remainder 3, not a factor
  • 122 ÷ 8 — remainder 2, not a factor
  • 122 ÷ 9 — remainder 5, not a factor
  • 122 ÷ 10 — remainder 2, not a factor
  • 122 ÷ 11 — remainder 1, not a factor

Why 122 has exactly 4 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.

122 = 2 × 61

(1 + 1) × (1 + 1) = 4

Step-by-step factorization: Prime factors of 122.
