Answers
Answer:
- Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers.
- Step 2: Write the number as a product of prime numbers.

Example:
Below is a detailed step-by-step process of prime factorization by taking 460 as an example.
Step 1: Divide 460 by the least prime number i.e. 2.
So, 460 ÷ 2 = 230
Step 2: Again Divide 230 with the least prime number (which is again 2).
Now, 160 ÷ 2 = 115
Step 3: Divide again with the least prime number which will be 5.
So, 115 ÷ 5 = 23
Step 4: As 23 is a prime number, divide it with itself to get 1.
Now, the prime factors of 460 will be 22 x 5 x 23
