(number 402 has 8 factors)

Factor Pairs of 402

A Factor Pair of number 402 is a combination of two factors which can be multiplied together to equal 402.

List of all possible Factor Pairs of 402:

  • 1 × 402 = 402
  • 2 × 201 = 402
  • 3 × 134 = 402
  • 6 × 67 = 402

How to find the Factors of 402

Divide 402 by every whole number from 1 up to 20. Each division without a remainder gives a factor and its pair. There is no point going further: 21 × 21 = 441 is already greater than 402, so any larger divisor would pair with a smaller one you have already checked.

  • 402 ÷ 1 = 402 — factors 1 and 402
  • 402 ÷ 2 = 201 — factors 2 and 201
  • 402 ÷ 3 = 134 — factors 3 and 134
  • 402 ÷ 4 — remainder 2, not a factor
  • 402 ÷ 5 — remainder 2, not a factor
  • 402 ÷ 6 = 67 — factors 6 and 67
  • 402 ÷ 7 — remainder 3, not a factor
  • 402 ÷ 8 — remainder 2, not a factor
  • 402 ÷ 9 — remainder 6, not a factor
  • 402 ÷ 10 — remainder 2, not a factor
  • 402 ÷ 11 — remainder 6, not a factor
  • 402 ÷ 12 — remainder 6, not a factor
  • 402 ÷ 13 — remainder 12, not a factor
  • 402 ÷ 14 — remainder 10, not a factor
  • 402 ÷ 15 — remainder 12, not a factor
  • 402 ÷ 16 — remainder 2, not a factor
  • 402 ÷ 17 — remainder 11, not a factor
  • 402 ÷ 18 — remainder 6, not a factor
  • 402 ÷ 19 — remainder 3, not a factor
  • 402 ÷ 20 — remainder 2, not a factor

Why 402 has exactly 8 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.

402 = 2 × 3 × 67

(1 + 1) × (1 + 1) × (1 + 1) = 8

Step-by-step factorization: Prime factors of 402.
