Answer: 4 and 7
Step-by-step explanation:
The LCM (least common multiple) of two numbers is the smallest number (different from zero) that is a multiple of both.
So, we need to find 2 numbers different from 28 that have 28 as a multiple and it has to be the least one, so this numbers must be smaller than 28.
If we look into all the numbers smaller than 28 that have 28 as a multiple we find: 2, 4, 7 and 14
The only 2 that have the LCM 28 are 4 and 7.
The only two numbers, neither of which is 28 but have an LCM of 28 are;
4 and 7
The LCM is an acronym for least common multiple.
Now, the LCM of two numbers is the smallest number that is not zero but is a multiple of both numbers.
We are told that 28 is not part of these 2 numbers but its' multiple must be 28. This means that the numbers must be less than 28.
Let us list the factors of 28 which are; 2, 4, 7, 14
Among those factors listed, the only 2 numbers that give an LCM of 28 are 4 and 7.
