Some stickers are in a packet.
If Adam puts them into groups of 8, there are 7 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 8: 8, 16, 24, 32, 40, 48, 56, 64
Multiples of 8 (+7): 15, 23, 31, 39, 47, 55, 63, 71
Multiples of 9: 9, 18, 27, 36, 45, 54, 63
Multiples of 9 (+8): 17, 26, 35, 44, 53, 62, 71
