Factors and Multiples

Front

What are factors of a number?

Back

Factors of a number are integers that can be multiplied together to produce that number. For example, the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.

Front

What are multiples of a number?

Back

Multiples of a number are the result of multiplying that number by integers. For example, the first five multiples of 8 are 8, 16, 24, 32, and 40.

How do you find the factors of a number?

Back

To find the factors of a number, divide the number by integers starting from 1 up to that number. If the division results in a whole number, both the divisor and the quotient are factors.

Front

What is a factor pair?

Back

A factor pair consists of two numbers that, when multiplied together, equal a given number. For example, (2, 12) is a factor pair of 24.

Front

What is the relationship between factors and multiples?

Back

Factors are the numbers that divide evenly into a given number, while multiples are the numbers that can be obtained by multiplying the given number by integers.

Front

List the first 5 multiples of 4.

Back

The first 5 multiples of 4 are 4, 8, 12, 16, and 20.

Front

How can you determine if a number is a factor of another number?

Back

A number is a factor of another number if the second number can be divided by the first number without leaving a remainder.

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor (GCF) is the largest integer that can divide two or more numbers without leaving a remainder.

Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) is the smallest integer that is a multiple of two or more numbers.

Front

How do you find the GCF of two numbers?

Back

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