  • 7 × 7 = 49

How to find the Factors of 49

Divide 49 by every whole number from 1 up to 7. Each division without a remainder gives a factor and its pair. There is no point going further: 8 × 8 = 64 is already greater than 49, so any larger divisor would pair with a smaller one you have already checked.

  • 49 ÷ 1 = 49 — factors 1 and 49
  • 49 ÷ 2 — remainder 1, not a factor
  • 49 ÷ 3 — remainder 1, not a factor
  • 49 ÷ 4 — remainder 1, not a factor
  • 49 ÷ 5 — remainder 4, not a factor
  • 49 ÷ 6 — remainder 1, not a factor
  • 49 ÷ 7 = 7 — factor 7, paired with itself

Why 49 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.

49 = 72

(2 + 1) = 3

Step-by-step factorization: Prime factors of 49.
