I'm not sure what you mean by lowest common factor, typically math teacher will ask for least common multiple or greatest common factor on your homework.While the lowest common factor is 1, 1 is also the greatest common factor. The least common multiple is 640.

The lowest common factor can not be larger than the lowest common factor. If you mean LCM (Lowest Common Multiple) and not LCF, the numbers are 5 and 150.
