**How to Find Factors of A Number**

In order to find the factor of a number, you will look for numbers that can completely divide the number completely.

**How to Find Prime Factors Of A Number**

- Find the smallest prime number that can divide the number completely without leaving a reminder.
- Similarly, divide the quotient of step 1 by the smallest prime number.
- Repeat step 2, until the quotient becomes 1.
- Finally, multiply all the prime factors that are the divisors.

Now, I will be providing solutions to the above question.

**What are Factors of 24**

The factors of 24 are the numbers that are multiplied in pairs resulting in the number 24. In other words, the numbers that divide 24 exactly are the factors of 24.

24/1 = 24

24 /2 = 12

24/3 = 8

24/4 = 6

24/6 = 4

24/8 = 3

24/12 = 2

24/24 = 1

So factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

**What are Prime Factors of 24**

The smallest prime number that can divide 24 completely is 2. 24/2 = 12. After that you will find another smallest prime number that can divide 12 completely. It is still 2, 12/2 = 6. Another smallest prime number that can divide 6 is 2, 6/2 = 3. Finally divide by 3 because 3 is the smallest number that can divide 3 without giving a reminder.
