You can start by dividing them by consecutive numbers. If the next number is the result of a division it means you're done

I'll find the divisors of 1000

1000 / 1 = 1000

1000 / 2 = 500

1000 / 4 = 250

1000 / 5 = 200

1000 / 8 = 125

1000 / 10 = 100

1000 / 20 = 50

1000 / 25 = 40

Now I'm done because the next number I could divide 1000 by is 40 but since I already have 40 it means I'm done

You can factorize the number too and use it to help you. 1000 = 2^3 x 5^3 by the way

By the way if the number is a square you divide it by every number you can until you reach its square root

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...

Is the number 14 a abundant perfect or deficient number?

14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28

What is a perfect Abundant Or dificient number?

A perfect number equals the sum of its proper divisors. A deficient number is greater than the sum of its proper divisors. An abundant number is less than the sum of its proper divisors. Proper divisors of a number do not include the number itself.
