Question

Find the HCF and LCM and verify12 and 18

Answer 1

Answer:

12 = 2 × 2 × 3

18 = 2 × 3 × 3

Therefore HCF = 3

And LCM = 3 × 2 ×2 × 2 × 3

= 72

LCM × HCF = 3 × 72 = 216

Product of two no.s = 12 × 18 = 216

hence LCM × HCF = product of two given no.s

Answer 2

please mark the answers brainleist

LCM of 12 and 18 - 2*2*3*3

HCF of 12 and 18- 2*3

verification :

LCM * HCF = 12*18

2*2*3*3*2*3= 216

216=216.
