In order not to have any leftover when cutting the ribbon of length 8 cm or 12 cm, the length of ribbon must be a multiple of 8 and 12.
Multiple of 8
8, 16, 24, 32, 40, 48 …
Multiple of 12
12, 24, 36, 48, 60,…
See that 24 is the first common multiple of 8 and 12. So, 24 is the smallest length of ribbon.
