The lcf (lowest common factor) of 6 and 8 is 1.

120

To find the greatest common factor and lowest common multiple of two numbers, you first need to split those numbers up into their prime factors. In this case: 8 = 2x2x2 12 = 2x2x3 The next step is to identify any common factors. In this case the common factors are two 2s. To find the greatest common factor, you multiply these together: 2x2 = 4. A quick way to find the lowest common multiple is to multiply the two original numbers together and divide by the greatest common factor. So 8x12/4 = 24. Thus 24 is the lowest common multiple.

The lowest common multiple is 24

The LCM is: 168
