Let a and b be two positive integers such that a = p3 q 4 and b = p2 q 3 , where p and q are prime numbers. If HCF(a,b) = pmq n and LCM(a,b) = pr q s , then (m+n)(r+s)= (a) 15 (b) 30 (c) 35 (d) 72

Let a and b be two positive integers such that a = p3q4 and b = p2q3 , where p and q areprime numbers. If HCF(a,b) = pmqn and LCM(a,b) = prqs, then (m+n)(r+s

If the LCM and HCF of two numbers are equal, then the numbers must be

The lcm of two prime numbers a and b is _________

1. Assertion : The HCF of two numbers is 5 and their product is 150, then their LCM is 30Reason : For any two positive integers a and b, HCF(a,b)+LCM(a,b) =axb.
