Question

Find the least perfect square number which is exactly divisible by 6 18 and 30

Answer 1

Answer:

900

Step-by-step explanation:

At first we have to calculate the LCM of 6 18 and 30 ie 90

on prime factorizing 90 we get

90=2 * 3 * 3 * 5=2 * 3² * 5

here we can see that the numbers 2 and 5 do not have pair. So 90 must be multiplied by (2*5)=10 to get the perfect square.

so 90*10=900 is the answer
