# Ratio of two numbers is 4:5 and their LCM is 220. Find the numbers.

Let’s consider the ratio of two number is Suppose P = 4 a and Q = 5 a and LCM of these two number is 20 a

According to the question LCM of these two number = 220

20 a = 220 a = 11

So the first no. is P = 11×4 and Q = 11×5

P = 44 and Q = 55
