Answer:

The LCM of #7# and #8# is #56#.

Explanation:

Well, the multiples of #7# are

#7,14,21,28,35,42,49,ul(56)#

and the multiples of #8# are

#8,16,24,32,40,48,ul(56)#

So you check your multiples and find your LCM by finding the numbers that match and whichever number is smaller and matches, that is your answer!
