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 9, there are 8 stickers left.
Find the smallest possible number of stickers in a packet.
Multiples of 7: 7, 14, 21, 28, 35, 42, 49
Multiples of 7 (+4): 11, 18, 25, 32, 39, 46, 53
Multiples of 9: 9, 18, 27, 36, 45
Multiples of 9 (+8): 17, 26, 35, 44, 53
Smallest possible number of stickers in a packet = 53
