## What common multiple means?

A common multiple is a whole number that is a shared multiple of each set of numbers. The multiples that are common to two or more numbers are called the common multiples of those numbers.

## What are common factors of 3 and 5?

The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15.

## How do you do Commons in maths?

In general: To factorise an algebraic expression, take out the highest common factor and place it in front of the brackets. Then the expression inside the brackets is obtained by dividing each term by the highest common factor.

## What are the multiple of 5?

Multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, etc. Each multiple is created by multiply 5 times some other number. Factors are the numbers used to create a multiple.

## What are the factors of 18?

## What is the GCF of x2 2x?

Step-by-step explanation: 1 Answer. The greatest common factor is 2x.

## How do you get rid of a common factor?

To remove a common factor and rewrite a polynomial as the product of a monomial and another polynomial: Find the greatest common factor which is a whole number (no variables). Divide all terms of the polynomial by that factor, and put the result in parentheses. Write the factor outside the parentheses.
