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 prime factors of a number or an algebraic expression are those factors which are prime.
How do you explain factors to a child?
Definition of Factors
Factors are numbers which you can multiply together to get another number . For Example : The numbers 2 and 3 are factors of 6 because 2 x 3 = 6. A number can have many factors!
How do you find the factors of a number?
- Find all the numbers less than or equal to the given number.
- Divide the given number by each of the numbers.
- The divisors that give the remainder to be 0 are the factors of the number.

The factors of 12 are 1, 2, 3, 4, 6, and 12 , because each of those divides 12 without leaving a remainder (or, alternatively, each of those is a counting number that can be multiplied by another counting number to make 12).
What is a factor of every number?
Factors: All the numbers that divide a number completely, i.e., without leaving any remainder, are called factors of that number. Multiples are those numbers which on multiplication gives the desired number. ... Therefore, 1 is the factor of every number.
How do you find the common factor of two numbers?
- If a factor appears in both lists then it is a common factor.
- For example, the factors of 8 are:
- The factors of 12 are:
- Therefore, the common factors of 8 and 12 are:
What are examples of factors?
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.
What is a factor in math definition 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.
