Explanation of number 140 Prime Factorization
Prime Factorization of 140 is expressing 140 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 140.
Since number 140 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 140, we have to iteratively divide 140 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 140:
The smallest Prime Number which can divide 140 without a remainder is 2. So the first calculation step would look like:
140 ÷ 2 = 70
Now we repeat this action until the result equals 1:
70 ÷ 2 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1
Now we have all the Prime Factors for number 140. It is: 2, 2, 5, 7
Or you may also write it in exponential form: 22 × 5 × 7
