Question

find the least square number exactly divisible by each one of the following number 8 9 1​

Answer 1

Answer:

72

Explanation:

we have to find the LCM of 8 9 1 which is

2³ & 3²= 72

Answer 2

We have to find the number which can be divided by both 8 and 9, we don’t take 1 as any number is divisible by 1. That means, 8 and 9 are the factors of that number, so we know the factors then we will be finding out the LCM of these numbers. That is 8*9= 72. But that isn’t a square so we take another bigger multiple than 72 that will be 72*2= 144.
So 144 is the least square number divisible by 8,9 and 1
