Question

fine the least square number divisible by each one of 8,9,10​

Answer 1

Answer:

Step-by-step explanation:

To find : Smallest Square number divisible by 8 , 9 , 10

Prime Factorization to find LCM,

8 = 2 × 2 × 2

9 = 3 × 3

10 = 2 × 5

LCM ( 8 , 9 , 10 ) = 2 × 2 × 2 × 3 × 3 × 5 = 360

Clearly 360 but it is not a perfect square number.

Now we make the pairs complete by multiplying same numbers in prime factorization of LCM.

We need one 2 and one 5 to complete the pair.

We get, Least Square number = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 3600

Therefore, Smallest Square Number is 3600.
