#### Answer

When you want to find factors, you need to look for numbers that multiply to get the number you are trying to find the factors for.
1x10=10, 2x5=10
Those are the only numbers that can multiply to get 10 so the factors are 1,2,5, and 10.
The best way to find factors is to divide it by the smallest prime number or to divide it by the numbers which don't make decimals. so...
10/1=10, 10/10=1, 10/2=5, 10/5=2
so the factors are 1, 2, 5 and 10

#### Work Step by Step

When you want to find factors, you need to look for numbers that multiply to get the number you are trying to find the factors for.
$1x10=10$, $2x5=10$
Those are the only numbers that can multiply to get 10 so the factors are 1,2,5, and 10.
The best way to find Factors, divide the numbers which don't make decimals. so
10÷1=10, 10÷10=1, 10÷2=5, 10÷5= 2
so...
The factors are: 1, 3, 5 and 10.
