Some stickers are in a packet.
If Adam puts them into groups of 7, there are 4 stickers left.
If Adam puts them into groups of 8, there are 3 stickers left.
Find the smallest possible number of stickers in a packet.
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63
Multiples of 7 (+4): 11, 18, 25, 32, 39, 46, 53, 60, 67
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64
Multiples of 8 (+3): 11, 19, 27, 35, 43, 51, 59, 67
Smallest possible number of stickers in a packet = 67
