Answer: False, the only factor is 1 (please look at explaination)
Step-by-step explanation: 4 and 5 only have one factor in common which is 1.
Factors of 4 are:
1, 2, 4
The factors of 5 are:
1, 5
The only common factor is 1. 1 is the common factor of all the numbers. Then we have variables xy, r. they do not have anything in common so I am sure that the answer is false.
Five stars please if the answer was correct.
