Question

If two positive ingeters a and b are expressible in the form a = pq² and b = p³q; p, q being prime number, then LCM (a, b) is

(a) pq
(b) p³q³
(c) p³q²
(d) p²q²

Answer 1

Two positive integers are expressed as follows:

p and q are prime numbers.

Then, taking the highest powers of p and q in the values for a and b we get:

LCM

Hence the correct choice is (c).
