Let Y be the smallest positive integer such that 12 and 8 are factors of 20*Y, So the value of Y is:	Choose the correct choice from the following choices
A) 7
B) 9
C) 11
D) 13
E) 15
You can calculate the LCM(12,8) (Least commom multiple of 12 and 8) = 36   and calculate the LCM(36,20) = 180   And making 180/20 we obtain 9.   So, the Answer is 9.
