The least common multiplier of A and B is 120, the ratio of A and B is 3:4, what is the largest common divisor?
How do u attack this problem? .. what are the approaches to take.
[spoiler]OA: 10
We know that A * B = LCM * GCD and we now LCM = 120.
So we get A *B = 120* GCD.
Now how does the ratio of the two numbers play out.
Pls explain in detail
