## What is a factor of 10?

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

## What are factors of 4?

4 = 1 x 4 or 2 x 2. Factors of 4: 1, 2, 4. Prime factorization: 4 = 2 x 2, which can also be written 4 = 2². Since √4 = 2, a whole number, 4 is a perfect square.

## Is 12 a factor or a multiple of 12?

## What is a factor for kids?

A factor is a number that you multiply with another number to get a product (the solution to a multiplication problem). Think of a multiplication problem as factors being multiplied to find the product. For instance, 2 and 4 are factors of 8: A number can have just two factors or many, many factors.

## What is a factor 4th grade math?

Factors are what numbers can be multiplied together to make another number (e.g., 1, 2, 3, and 6 are factors of 6). … Multiples are what you get after multiplying a number by an integer (e.g., 20 is a multiple of 4).

## How do you reduce a number by a factor of 10?

Very simply, to increase something by a factor of 10 is to multiply it by ten. The reverse applies for a reduction; if, for example, there are 230 mice in a warehouse, and cats reduce this by a factor of 10, then one may assume that there are just 23 remaining alive.

## How do you find a factor in math?

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
