Question

find the smallest square number which is exactly divisible by each one the following number 5,9,12 ? please give me answer for 3 marks in practical way​

Answer 1

Answer:

the answer is 3600.

Step-by-step explanation:

The least square number which is exactly divisible by 8, 9, and 10 = L.C.M. of 8, 9, and 10.

Hence,L.C.M = 2×2×2×3×3×5=360

As we calculate,

2×2×2×3×3×5

2 and 5 have incomplete pairs.

So, to make if perfect square, we have to multiple it by

2 × 5 = 10

Now, 360 ×10 = 3600

Answer 2

Answer:

it is 30 square is 900

Step-by-step explanation:

because 900 is divisible by 9

and also by 5

and also by 12

so the right answer is 30²
