Answer:
Step-by-step explanation:
Tip: For a no. to be a perfect square each factor in its L.C.M must occur in pair.
Take out the L.C.M of 69192 which is = 2*2*2*3*3*31*31
=2^2 * 3^2 * 31^2 * 2
Since one of the 2 does not have a pair. We would multiply 69192 with 2 to make it a perfect square .
=69192*2= 138384
=√138384=372
Ans. The least no. would be 2
