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 divisors of 145 are 1, 5, 29, 145.
The single-digit divisors of 7,000 are 1, 2, 4, 5, 7, 8.
The two numbers between 5 and 20 that are almost perfect are 6 and 28. An almost perfect number is a number that equals the sum of its proper divisors, excluding itself. The proper divisors of 6 are 1, 2, and 3, which sum up to 6. Similarly, the proper divisors of 28 are 1, 2, 4, 7, and 14, which sum up to 28.
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.
80 has 10 divisors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
1, 2 and 4
The divisors of 40: 1 | 2 | 4 | 5 | 8 | 10 | 20 | 40 (8 divisors)
The divisors of 500 are: 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500.
12 divisors: 1 2 4 5 10 11 20 22 44 55 110 220.
200 has 12 divisors: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200.
Here are all nine of 100's divisors: 1, 2, 4, 5, 10, 20, 25, 50, 100.
