'Prime factors' for 4th grade
4th grade / Multiply + Divide / Prime factors / Prime factors
Identify prime factors
Prime numbers are special numbers that can only be divided by 1 and the number itself without leaving a remainder. In other words, they have exactly two factors. So the number 3 is a prime number because it is divisible only by 3 and 1. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19. Many numbers are not prime, they are composite numbers - numbers that have more than two factors. These numbers can be divided by different numbers, not just 1 and themselves. For example, 4 can be divided by 1, 2, and 4.
Prime factorization is a way to break down a composite number into smaller pieces that are all prime numbers. These smaller prime numbers are called "prime factors". To work out the prime factors of a number, start with the smallest prime number, 2, and see if it divides the given number without leaving a remainder. If it does, write down the number 2 and the result of the division. If it doesn't, move on to the next smallest prime number, 3, and try again. Repeat this process until you've found all the prime factors.
What are the prime factors of 10?
- First, divide 10 by the smallest prime number, which is 2.
- 10 ÷ 2 = 5. The result is another prime number, 5.
- So, the prime factors of 10 are 2 and 5 (10 = 2 x 5).
The prime factors of 10 are 2, 5
What are the prime factors of 60?
60 can be divided by 2 without leaving a remainder: 60 ÷ 2 = 30. Write down 2 and 30.
Now, check if the result (30) can be divided by 2 without leaving a remainder: 30 ÷ 2 = 15. It can, so write down 2 and 15.
The result (15) cannot be divided by 2, so move on to the next smallest prime number, 3. Check if 15 can be divided by 3 without leaving a remainder: 15 ÷ 3 = 5. It can, so write down 3 and 5.
The result (5) is a prime number, so we've found all the prime factors:
The prime factors of 60 are 2, 3, 5
In this topic you are asked to find the prime factors of numbers from 6 to 100.

With our Pong math game you will be practicing the topic "Prime factors" from 4th grade / Multiply + Divide / Prime factors. The math in this game consists of 16 questions that ask you to identify the prime factors of numbers up to 105.
In our version of Pong/Breakout, there are 3 types of bricks for you to break: green bricks are worth just 2 points; yellow bricks are worth a whopping 50 points; breaking white bricks, which are worth 10 points, wins you a math question from the topic you have chosen.
You start with 5 lives. If the ball goes below the paddle, you lose a life and 200 points. The game ends when you answer all 10 questions or lose all your lives.
Notes
- This version of Pong is a one player game to learn or revise math
- Our PONG for math is a scoring game - play a few times and set a personal best score!
