How Do You Find All Factors Of A Number?
When you multiply two numbers together to get a third number, the first two numbers are called factors of the third number. For example, 3 times 5 equals 15. Therefore, 3 and 5 are factors of 15. In another example, 1 times 15 equals 15. Therefore, 1 and 15 are factors of 15. In fact, for every number, one and that number are factors of the number. The best way to find all the factors of a number is to approach the problem methodically. That way, you won’t miss any of the factors. Write “1” on the left side of your paper. On the right side, write the number you are factoring. For example, if you are factoring the number 15, then write “15.” Decide if 2 is a factor of your number. Ask yourself if you can divide your number evenly by 2. If you are factoring 15, then 2 is not a factor because 15 divided by 2 equals 7 with a remainder of 1. If there is a remainder, the number is not a factor. Decide if 3 is a factor of your number. In our example, 3 is a factor because 15 divided by 3 equa
