A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.
There are two different methods that can be used for the prime factorization.
To find the primefactors of 420 using the division method, follow these steps:
So, the prime factorization of 420 is, 420 = 2 x 2 x 3 x 5 x 7.
We can follow the same procedure using the factor tree of 420 as shown below:
So, the prime factorization of 420 is, 420 = 2 x 2 x 3 x 5 x 7.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 420 would be the two numbers which, when multiplied, give 420 as the result.
