Explanation of number 1980 Prime Factorization
Prime Factorization of 1980 it is expressing 1980 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 1980.
Since number 1980 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 1980, we have to iteratively divide 1980 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 1980:
The smallest Prime Number which can divide 1980 without a remainder is 2. So the first calculation step would look like:
1980 ÷ 2 = 990
Now we repeat this action until the result equals 1:
990 ÷ 2 = 495
495 ÷ 3 = 165
165 ÷ 3 = 55
55 ÷ 5 = 11
11 ÷ 11 = 1
Now we have all the Prime Factors for number 1980. It is: 2, 2, 3, 3, 5, 11
Or you may also write it in exponential form: 22 × 32 × 5 × 11
