How to Factor 12?
To calculate the factors of 12, follow the given steps:
- Step 1: Write 12
- Step 2: 12 is a multiple of 6 and so write 12 as 6 Ã— 2
- Step 3: Factor 6 as 2 and 3
- Step 4: Write 12 = 2 Ã— 3 Ã— 2
- Step 5: Now multiply all the multiples to get all the factors of 12
Prime Factors of 12
The prime factors of 12 are the prime numbers from the list of factors for the number 12. The prime factors of 12 can also be obtained by another method which is explained below. Here are all the prime factors of 12:
- Prime Factors of 12 = 2 X 2 X 3
How To Calculate Prime Factor of 12?
To calculate the prime factors of 12, divide it with the least prime number which is 2. When it cannot be divided further with two, divide it with the next prime number which is 3 in this case till the end product is 1. This is called prime factorization of a number and a step by step format for 12 is given below.
- Step 1: Divide 12 with 2
- 12 Ã· 2 = 6
- Step 2: Again divide 6 with 2
- 6 Ã· 2 = 3
- Step 3: Since 3 is no more divisible by 2, move to the next prime number i.e. 3
- 3 Ã· 3 = 1, We get 1
From the above steps, it can be said that the prime factor of 12 will be 2 Ã— 2 Ã— 3 i.e. 2^{2} X 3. It should be noted that the above-mentioned method will not only work for 12 but even for all the large numbers like Prime Factors for 36 etc also.
