2.What is Prime Factorization?
The way to express numbers as products of their own prime factors is known as Prime Factorization. It is the process to write the number as the product of its prime numbers. Prime numbers are the ones that exactly have two factors, one of them is 1 and the other is the number itself.
For example, if we take the number 40, we know that 40=10 x 4 is not a prime number. Both the numbers 10 and 4 can be further factorized as 5 x 2 and 2 x 2 respectively. Here both the numbers 5 and 2 are prime numbers.
Therefore, Prime Factorization of 40 will be 5 x 2 x 2 x 2 which is 5 x 2^{3}.
Further, there are two ways Prime Factorization can be done-
Using Factor Tree Method
Using Division Method
