The highest power of the variable in a polynomial is called its degree.

A common factor of two or more numbers is a number that divides each of the given numbers exactly, without leaving any remainder.

A factor of a number is any number that divides the given number completely without leaving a remainder.

or

When two numbers are multiplied, the result is called their product, and the numbers that are multiplied are called factors of the product.

The terms that do not have the same literal coefficients are called unlike terms. 

For example:

6a, 6ab and 6ac are unlike terms. 

Terms having the same literal part (same variables with the same powers) are called like terms.

For example:

xy, 5xy, -4xy, etc. are like terms
