Question 1:
The ratio of two numbers is 3 : 4 and their H.C.F. is 4. Their L.C.M. is: A. 12
B. 16
C. 48
Feedback Let the numbers be 3x and 4x.
Then, their H.C.F. = x. So, x = 4. So, the numbers 12 and 16.
L.C.M. of 12 and 16 = 48.
Then, their H.C.F. = x. So, x = 4. So, the numbers 12 and 16.
L.C.M. of 12 and 16 = 48.
D. 42
