Question

Hcf and lcm of 180 and 336

Answer 1

Answer:

Find the prime factorization of 180

180 = 2 × 2 × 3 × 3 × 5

Find the prime factorization of 336

336 = 2 × 2 × 2 × 2 × 3 × 7

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 7

LCM = 5040

HCF :

336 = 180*1 + 156

180 = 156*1 + 24

156 = 24*6 + 12

24 = 12*2 + 0

HCF = 12
