Question

21. If GCD of two number is 8 and LCM is 144, then what is the second number if first

number is 72?​

Answer 1

Answer:

What's GCD it should be HCF

HCF = 8

LCM = 144

IF 1ST NUMBER = 72

THEN 2ND NUMBER BE X

SO

= LCM× HCF = 1ST NO. × 2ND NO.

= 144 × 8 = 72 × X

= 144×8 /72 = X

= 2×8 = X

= 16 = X

OR 2ND NUMBER = 16
