Because is shows 1020 is divisible by 10 and everything that divides by 10, also divides by 5 and 2, because 10 itself divides by 5 and 2.
10 and 5 can divide into 1000 and 400000
The number that divides into 130 and 85 is 5.
10 = 2*5, a product of 2 primes, and 2 divides (5-1). So there are only two groups.
2, 4, 5, 8, 10, 20, 25, 40, 50, 100
5.. divides into 5 and 10.

1, 2, 5, 10.
10 and 5 can divide into 1000 and 400000
30, 15, 10. 6, 5, 3, 2 and 1.

The number that divides into 130 and 85 is 5.
The greatest common factor of 10, 15, and 30 is 5.5
1, 2, 3, 4, 5, 6, 9, 10, 12, ...60
All of these: 1, 2, 5, 10, 37, 74, 185, 370.
110 divides by these numbers: 1, 2, 5, 10, 11, 22, 55, 110.
10 = 2*5, a product of 2 primes, and 2 divides (5-1). So there are only two groups.
