So, the smallest square number that can be divided by 6, 9 and 15 is 900.

## What is the least perfect square number exactly divisible by each number 6 9 and 15?

Therefore 3600 is the perfect square and the smallest perfect square exactly divisible by 6,9,15 and 20.

## Which is the smallest square number divisible by 4 9 and 13?

Hence the LCM of numbers 4,9,10 is180, where 180 is not a perfect number. Hence the number 900 is the smallest square number divisible by each number 4, 9, and 10.

## What is the smallest square number which is divisible by?

L.C.M. of 8, 15 and 20 is 120. Here, prime factors 2, 3 and 5 have no pair. Therefore 120 must be multiplied by 2 x 3 x 5 to make it a perfect square. Hence, the smallest square number which is divisible by 8, 15 and 20 is 3600.

## What is the smallest perfect square number divisible by 15 18 and 25?

Hence, 900 is the number which is divisible by 15,18 and 25 and is a perfect square.

## What is the least square number?

From here, we obtain lcm(10,12,16)=24×3×5, hence the least square number required is 24×32×52=3600.

## What least number must be added to 5607 to make it a perfect square?

Answer. Therefore, you must add 18 to 5607 to get the sum to be a perfect square.

## What is the lowest common multiple of 4 9 and 10?

Answer: LCM of 4, 9, and 10 is 180.

## Which is the smallest square number divisible by 4 9 and 10?

Hence, the smallest square number which is divisible by 4, 9 and 10 is 900.

## IS 90 is a perfect square?

No because 90 cannot be written in the form of product of two equal numbers so it is not a perfect square. For e.g. 81 can be written in the form 9×9 hence it is a perfect square.

## What is a perfect square called?

In mathematics, a square is a product of a whole number with itself. For instance, the product of a number 2 by itself is 4. In this case, 4 is termed as a perfect square. A square of a number is denoted as n × n.
