Factor Pairs of 210

A Factor Pair of number 210 is a combination of two factors which can be multiplied together to equal 210.

List of all possible Factor Pairs of 210:

  • 1 × 210 = 210
  • 2 × 105 = 210
  • 3 × 70 = 210
  • 5 × 42 = 210
  • 6 × 35 = 210
  • 7 × 30 = 210
  • 10 × 21 = 210
  • 14 × 15 = 210

How to find the Factors of 210

Divide 210 by every whole number from 1 up to 14. Each division without a remainder gives a factor and its pair. There is no point going further: 15 × 15 = 225 is already greater than 210, so any larger divisor would pair with a smaller one you have already checked.

  • 210 ÷ 1 = 210 — factors 1 and 210
  • 210 ÷ 2 = 105 — factors 2 and 105
  • 210 ÷ 3 = 70 — factors 3 and 70
  • 210 ÷ 4 — remainder 2, not a factor
  • 210 ÷ 5 = 42 — factors 5 and 42
  • 210 ÷ 6 = 35 — factors 6 and 35
  • 210 ÷ 7 = 30 — factors 7 and 30
  • 210 ÷ 8 — remainder 2, not a factor
  • 210 ÷ 9 — remainder 3, not a factor
  • 210 ÷ 10 = 21 — factors 10 and 21
  • 210 ÷ 11 — remainder 1, not a factor
  • 210 ÷ 12 — remainder 6, not a factor
  • 210 ÷ 13 — remainder 2, not a factor
  • 210 ÷ 14 = 15 — factors 14 and 15

Why 210 has exactly 16 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.

210 = 2 × 3 × 5 × 7

(1 + 1) × (1 + 1) × (1 + 1) × (1 + 1) = 16

Step-by-step factorization: Prime factors of 210.
