What is the prime factorization of 230?
We can work through the prime numbers.
Consider the first prime number 2. We ask ourselves if 230 is divisible by 2 and yes it is. So divide by 2 and we get: 115.
We now ask if 115 is divisible by 2 but it is not. So we move onto the next prime number, 3.
115 is not divisible by 3, so we move onto 5. 115 is divisible by 5 so we factor out 5 to obtain:
23 itself is a prime number so we have completed the prime factorisation.
