1, 2, 4, 5, 10, 20.
1 is a divisor of all whole numbers so 1 is also included necessary to be included (if 20 is a divisor of 20, what is 20/20)
The divisors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
The divisors of 97 are: 1, 97.

The single-digit divisors of 7,000 are 1, 2, 4, 5, 7, 8.
Eight has four divisors (factors): 1, 2, 4, 8.
2,835 has 20 divisors.
The divisors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40.
The divisors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40.
Because the sum of its proper divisors is greater than 20.
The divisors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

1, 2 and 4
I'm going to give an example... If you were trying to find the divisors of 20, you would need to do something like... 20 divided by 1, 2, 3, 4, 5,... until you get to 20...
12 divisors: 1 2 4 5 10 11 20 22 44 55 110 220.
The divisors of 500 are: 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500.
The divisors of 40: 1 | 2 | 4 | 5 | 8 | 10 | 20 | 40 (8 divisors)
