Q18 of 44 Page 1

Find HCF and LCM of 404 and 96 and verify that HCF x LCM = Product of the two given numbers. (CBSE 2018)

Prime Factorising the given numbers:

404 = 2 × 2 × 101


96 = 2 × 2 × 2 × 2 × 2 × 3

Now,
H.C.F = Multiplication of common factors of numbers. Therefore, 

HCF = 2 x 2
L.C.M = Multiplication of all the factors of numbers. Therefore,


LCM = 2 x 2 × 101 × 2 × 2 × 2 × 3


= 9696


HCF x LCM = 9696×4 = 38784


= 404×96 = Product of Two Numbers


Hence, Verified.
