Given that a, b and c are distinct prime no. greater than 10 and the product of P= 10*a5*b5 and Q= 50*a10*c is Y. Find the no. of common multiples of P and Q which are factors of Y?
option
A. 16
B. 24
C. 36
D. 48

• LCM of P and Q = 50.a10.b5.c1
  
  and product of P and Q is Y = 500.a15.b5.c1
  
  I think ans is 10x6 = 60
