The first number of two is 45.

1) The ratio of given two numbers is 3:4.

2) Let the numbers be 3x and 4x.

3) The factors of 3x are 3 and x .

The factors of 4x are 2,2 and x

4) The LCM of 3x and 4x would be 12x

5) But the given LCM of numbers is 180.

6) Equating both, 12x = 180

x = 15.

7) Hence, the numbers are 3*15 = 45 and 4*15 = 60
