Question

Find the least square number exactly divisible by each one of the numbers 6,9,10,15,20

Answer 1

LCM of 6,9,10,15,20 is 180
Now,
Least no = 180
Square of least no. =180^2= 32400
Ans is 324000

Answer 2

Since it is given that we have to find the least square number so clearly first ,we have to find out the LCM of 6,9,10,15,20. We can find it by the prime factorisation method. so the LCM of these numbers =2×2×3×3×5=180
now since we have to find the least "square' number so now we will take out the square of the LCM of these numbers:-
so 180^2=32400
