Question

find HCF of 90 and 126 by euclid's division algorithm also find their LCM and verify that LCM . HCF is equal to product of two numbers

Answer 1

HCF

126=90*1 + 36.

90=36*2 + 18

36=18*2 + 0

HCF(126, 90) is 18.

126= 2*3*3*7

90= 2*3*3*5

LCM(126,90)= 3*3*2*5*7 = 630

LCM*HCF = A*B

630*18 = 126*90
1134=1134

Hence Proved.
