For example, if you recite the multiplication formula, you will know that only 2 and 5 can be divisible by 10, and both 2 and 5 can be divisible by other numbers except itself and 1, so the divisor of 10 is 1, 2,5,/kloc.
Another example is 60, and the minimization numbers are 2, 2, 3 and 5 respectively. Then, 2 * 2 = 4, 2 * 3 = 6, 2 * 5 = 10, 3 * 5 = 15, 2 * 2 * 3 = 12, 2 * are respectively.
So all the divisors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 30, 60.
