Question

Find the H.C.F of 54,144 and 210 using any method.​

Answer 1

Find the prime factorization of 144

144 = 2 × 2 × 2 × 2 × 3 × 3

Find the prime factorization of 210

210 = 2 × 3 × 5 × 7

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3

GCF = 6
