what is the least common factor for 18 and 8?
610495
18, 36, 54, 72, 90, 108, 126, 144 . . . By comparing the multiples of eight and eighteen, we can see that the smallest one that they share is 72. Thus, the LCM of 8 and 18 is 72. Because the LCM is 72, this means that every multiple of 72 is also a multiple of both 8 and 18.
