Question

Find the LCM and HCF of the following pairs of integers and verify that LCM×HCF= product of the two numbers is (1). 510 and 92

Answer 1

LCM of 510 is 2*3*5*17

LCM of 92 is 2*2*23

.•. LCM of 510 and 92 is = 2

HCF of 510 = 2*3*5*17

HCF of 92 = 2*2*23

HCF of 510 and 92 is = 23460

LCM * HCF = Product of no.

2 * 23490 = 46490

product of 2 no. = 510 * 92

= 46490

.•. Thus proved
