How to Find the Factors of 132?
To find the factors of 132 using the division method efficiently, you only need to check numbers up to the square root of 132. For every number that divides 132 evenly, both it and its corresponding pair (132 ÷ that number) are factors.
Optimized steps to find factors of 132:
- •132 ÷ 1 = 132 → ✅ Factor Pair: (1, 132)
- •132 ÷ 2 = 66 → ✅ Factor Pair: (2, 66)
- •132 ÷ 3 = 44 → ✅ Factor Pair: (3, 44)
- •132 ÷ 4 = 33 → ✅ Factor Pair: (4, 33)
- •132 ÷ 6 = 22 → ✅ Factor Pair: (6, 22)
- •132 ÷ 11 = 12 → ✅ Factor Pair: (11, 12)
This method avoids unnecessary checks and gives all factor pairs quickly. It's especially useful for larger numbers.
