Is 200 an abundant number

Answer 1

The prime factors of 200 are 2 x 5 x 2 x 5 x 2. All possible multiples of those are all of 200's divisors. If you calculate all the divisors and add them up you will get the sum of divisors for 200. If that sum is greater than 400, then 200 is abundant.

Here are a few examples of 200's divisors:

200, 100, 2, 50, 4, 8, 25. Already those add up to 391... if there are any more then 200 is certainly abundant.
