Question

find the smallest square number that is divisible by each number 7and14and18​

Answer 1

Answer

1764

Step-by-step explanation:

7= 7 times 1

14= 1 times 14 or 2 times 7

18= 1 times 18, 2 times 9 or 3 times 614

We can ignore 7 as 7 is a factor of 14

The LCM of 14 and 18 is 126

126 consists of 3 times 3 times 2 times 7

So we need 2 times 7 and we can multiply it to 126 so we have a pair of 3, a pair of 2 and a pair of 7

Therefore, the answer is:

3 square times 2 square times 7 square
