Common Factor or Multiple? And, I think you phrased your question wrongly.

Re: E Maths Question Need Help

For common multiple, the single number, in this case, your 2160 have to be smaller than your other numbers, in this case 48, 180, and K.

For common factor, the smallest is always 1. Therefore, there is no Lowest common Factor.

Thus, I do not understand your question.
