The lowest common factor of 6 and 15 is 1.

However, I suspect you either want their lowest common multiple (ie the smallest number into which both 6 and 15 divide) or their highest common factor (the largest number which will divided into both 6 and 15).

LCM:

6 = 2 x 3

15 = 3 x 5

LCM = 2 x 3 x 5 = 30

HCF:

6 = 2 x 3

15 = 3 x 5

HCF = 3.
