- Which three numbers below are all co-prime with each other?

Select three answer choices.

The answer said 100 143 and 154, but can’t it also be 75, 143, and 154?

143 and 154 share a common factor

can 100,143,147 be the answer??? three of them doesn’t have common factor more than 1 with each other.

The answer should actually be 100, 143 and 147.

143 and 154 share 11 as common factor and therefore are not coprime.
