Some stickers are in a packet.
If Adam puts them into groups of 7, there are 3 stickers short.
If Adam puts them into groups of 6, there are 5 stickers short.
Find the smallest possible number of stickers in a packet.
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70
Multiples of 7 (-3): 4, 11, 18, 25, 32, 39, 46, 53, 60, 67
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Multiples of 6 (-5): 1, 7, 13, 19, 25, 31, 37, 43, 49, 55, 61, 67
