Let the smaller number be 5x and the bigger number be 6x. We are given the L.C.M. of the two numbers is 660. Now, we can use the formula: L.C.M.×H.C.F.=Product of the two numbers From the ratio, the L.C.M. = 30x and we are told L.C.M. = 660. Hence, 30x=660 x=22 So, the smaller number = 5x = 5 × 22 = 110. Therefore, the smaller number is 110.
