18
The LCM of the two numbers is 126
Work out two possible values for the blank card.

I have 7 but I don’t k so the other number

Answer 1

7 and 14

Explanation:

Given the LCM of two numbers to be 126

If one of the numbers is 18

The other number will be 126/18 = 7

The other possible value can be gotten by multiplying the lowest prime number by 7 i.e 2×7= 14

The two possible numbers are 7 and 14
