Question

find LCM and HCF of 120 and 144 by fundamental theorem of arithmetic

Answer 1

120=2x2x2x3x5

144=2x2x2x2x3x3

HCF=2x2x2=8

LCM=2x2x2x2x3x3x5=720

Answer 2

Step-by-step explanation:

120 = 2 x 2 x 2 x 3 x 5

144 = 2 x 2 x 3 x 3 x 2 x 2

HCF = 2 x 2 x 2 x 3 = 8 x 3 = 24

LCM = 2 x 2 x 2 x 2 x 3 x 3 x 5

        = 16 x 9 x 5

        = 720

Hope it helps!!
