Question

Given that H.C.F of 420 and 272 is 4.find the LCM of (420,272)

Answer 1

Sol:
By using Euclid 's division algorithm

4052 = 420×9 + 272

420 = 272×1 + 148

272 = 148×1+124

148 = 124×1 + 24

124 = 24×5 + 4

24 = 4×6 + 0.

Therefore,4 is the HCF of 4052 and 420.

Answer 2

hi frnd here is ur ans,
hcf ×lcm= product of 2 Nos.
4×lcm=420×272
lcm =28560
