5th grade / Multiply + Divide / Factors / Prime factors
Factors are numbers that divide into a number without a remainder. The factors of 12 are 1, 2, 3, 4, 6 and 12. Prime factors are the factors of a number that are prime numbers (numbers that can only be divided evenly by 1 and themselves).
To find the prime factors of a number, first list all of it's factors, then decide which of them are prime. Express the number as a product of it's prime factors.
So, in the first question from the lesson we have the number 6. The factors of 6 are 1, 2, 3 and 6, and the prime factors are 2 and 3 (1 is not considered a prime number).
Starting with the smallest prime factor, divide the original number by that value, and continue to do so until the result is no longer divisible by that prime factor without a remainder. Move to the next largest prime factor and continue until you have the original number expressed as a product of it's prime factors.
Prime factors of 6: 2 x 3
Prime factors of 20: 2 x 2 x 5
Prime factors of 48: 2 x 2 x 2 x 2 x 3
Prime factors of 21: 3 x 7
With our Four in a row math game you will be practicing the topic "Prime factors" from 5th grade / Multiply + Divide / Factors. The math in this game consists of 16 questions that ask you to identify the prime factors of each number up to 99.
The game will reinforce the math you have chosen to learn by getting you to match the question to the correct answer.
