Question

if a is odd number b is not divisible by 3 and lcm of a and b is p then lcm of 3a and 2b is

Answer 1

LCM of 3a and 2b will be 6p.

Since a is odd, it is not divisible by 2(so we need to multiply 2(from 2b) with the lcm of a and b.)
And since b is not divisible by 3, we need to multiply 3(from 3a) with the lcm of a and b.

So LCM of 3a and 2b = 2×3×(lcm of a and b) = 6p

Answer 2

• thus the lcm of 3a and 2b is 6p
