To find the GCF, list the factors of each number and identify the largest factor that appears in both lists.

Place value is the value of a digit based on its position in a number. For example, in 3,180, the '3' is in the thousands place.

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a number by a sum by distributing the multiplication.

The LCM is the smallest number that is a multiple of both numbers. You can find it by listing the multiples or using prime factorization.

A factor is a whole number that can be divided evenly into another number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12.

Dividing evenly means that there is no remainder when one number is divided by another. For example, 12 divided by 4 equals 3 with no remainder.

A common multiple is a number that is a multiple of two or more numbers. For example, 24 is a common multiple of 8 and 12.

You can group numbers in a way that makes them easier to add. For example, 42 + 54 can be simplified using 6(7 + 9).

Factors are numbers that divide another number evenly, while multiples are the result of multiplying a number by whole numbers.
