Question

Use prime factorization to find the HCF and the LCM of 100 and 132​

Answer 1

Both of these are even numbers 2 seems like the best number

Answer 2

HCF=4 and LCM=3300

Explanation:

2 ^2 ×3^1 ×5^2 ×11^1=3300

so the LCM of 100 and 132 is 3300

100 = 2 × 2 × 5 × 5

132 = 2 × 2 × 3 × 11

So the HCF is 2x2 which equals to 4
