Step 1
First, write a list of the multiples of each number like so:
4: 4,8,12,16,20,24,28,32,36,40,44,48,52,56
7: 7,14,21,28,35,42,49,56,63,70,77
Then you find the first number which 4 and 7 have in common. 4 and 7 have 28 and 56 in common but the LCM would be 28 since that's the least common, or the smallest number that would have in common.
