How about: 80
Both 7 and 16 can go into their least common multiple (LCM), which is 112. This means that any multiple of 112, such as 112, 224, or 336, can be evenly divided by both 7 and 16. Additionally, they can both go into any number that is a common multiple of both.
The number that both 7 and 8 can go into evenly is 56.
1, 2, 4, 8, 16.
The numbers that can go evenly into both 3 and 16 are their greatest common divisor, which is 1. Since 3 is a prime number and does not share any other factors with 16 (which is a product of 2's), the only common factor is 1. Therefore, the only number that can go into both 3 and 16 is 1.

These numbers go evenly into both 800 and 160 evenly: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160.
1, 2, and 3 for both 16 and 30.
3 and 1 will go into both number evenly leaving no remainders.
