what do they mean by dividing evenly??
A divides B evenly if it leaves a remainder 0, when it divides B.
If k=m(m+4)(m+5) k and m are positive integers. Which of the following could divide k evenly?
I.3
II.4
III.6

If m = 1, then k = 1*5*6. So, 3 and 6 are factors of k
If m = 4, then k = 4*8*9. So, 4,3 and 6 are factor of k.

The answer to this question is ALL THE ABOVE. If the question is 'Which of the following MUST divide k evenly?', then the answer is I and III.

If we're told that integer x divides evenly into integer k, we can say that x is a divisor of k.

The term "divides evenly" is not the best, since it suggests that the quotient k/x is even. This need not be the case.
