Factors can also be found by determining what two whole numbers, when multiplied together, equal the number you are factoring. The proper factors are all the factors of a certain number except that number itself!

## What is proper and improper divisor?

Proper divisors: A number x is a proper divisor of y provided that x is a divisor of y and x is less than y. So the only "improper" divisor of a number is the number itself; all other divisors are proper. The Greeks classified numbers according to the sums of their proper divisors.

## Which integer has the most divisors?

Hence, 176 has the most number of divisors.

## How do you find the divisors of a number in Java?

To get the divisor of a number N, we should divide N by all numbers in between 1 and N including 1 and N. We will use modulus operator which gives reminder. If reminder is zero, we can say given number is divisible by another number. For ex: 10%2= 0 (10 is divisible by 2 without a reminder)
