Prime Factoring

Prime factoring

A composite number written as the product of prime numbers is called the prime factoring.

Example 1:

The prime factoring of 168 is 2 × 2 × 2 × 21, or 2³ × 21.

Note:

2 is a prime number and 21 is a prime number.

Example 2:

The prime factoring of 150 is 2 × 5 × 3 × 5, or 2 × 3 × 5².

Note:

2, 3 and 5 are prime numbers.

The technique is very useful when simplify fractions.
