How to find the factors of 67
Test every whole number from 1 up to the square root of 67 (√67 ≈ 8.185). Each number that divides evenly gives you two factors at once: the divisor and the quotient.
- 67 ÷ 1 = 67 — so 1 and 67 are factors
- 67 ÷ 2 = 33.5 — not a whole number
- 67 ÷ 3 = 22.333 — not a whole number
- 67 ÷ 4 = 16.75 — not a whole number
- 67 ÷ 5 = 13.4 — not a whole number
- 67 ÷ 6 = 11.167 — not a whole number
- 67 ÷ 7 = 9.571 — not a whole number
- 67 ÷ 8 = 8.375 — not a whole number
Collecting both numbers from every successful division gives the complete list: 1 and 67.
