Question

the answer would be
a×b = LCM (ab) × HCF (ab)
24×b =12×312
Answer would be (b = 156)

Answer 1

Answer:

b=156

Explanation:

24×b=12×312

or,2×12×b=12×312

or,12×2b=12×312

Hence, 2b=312

or, b=312/2

or, b=156.

So the answer is b=156

Answer 2

Answer:

simply we can calculate

24×b=12×312

b=12×312/24=156
