Commutative property It makes no difference in which order two numbers are multiplied. The commutative property does not apply to division
Factor One of two or more numbers that are multiplied together to obtain a product. Factors are whole numbers which can be divided exactly into a given number.
Multiple A multiple of a number is the product of that number and an integer.
