How to factorize number manually
In order to break down a number into prime factors, divide it by prime numbers beginning with the smallest until result is 1.
Steps:
- Check if the number can be divided by 2 without remainder (if the number is even, divide it sequentially by 2 while possible).
- Take the result of division and check if it can be devided by next prime number.
- Repeat until you get 1 in result.
- If the result > 1 and it cannot be divided by any number, it is a prime number itself.
Factorize number 24:
- 24 ÷ 2 = 12
- 12 ÷ 2 = 6
- 6 ÷ 2 = 3
- 3 ÷ 3 = 1
24 = 2 × 2 × 2 × 3 = 23 × 3
