You divide by prime numbers until you get to 1, and then the numbers you divided by are the prime factors.
eg: 660
It's even so I divide by 2 and get 330
That's even so I divide by 2 and get 165
That ends in 5 so I divide by 5 and get 33
I know that divides by 11 so I divide it by 11 and get 3
Divide that by 3 and get 1.
I divided by 2,2,5,11 and 3, so those are the prime factors of 660.
To find the prime factors of any number then divide the number by prime numbers of increasing value. When a prime number wholly divides the original number repeat the process with the same prime number but each time with the new quotient until complete division does not occur. Repeat with a prime number of higher value until the final quotient is 1. Using this process gives the prime factors of 374 as 2, 11 and 17.

The factors are 1, 5, 37, and 185. Factoring 185: 185 is actually an easy number to factor (or break down) into primes.1. This is done using division. The first step is to divide 185 by some small number that you know is prime. Clearly, 185 is divisible by 5. Do that division.2. Because 185 is evenly divisible by 5, and 5 is a prime number, then 5 is a prime factor of 185. If there's anything that you take away from this answer here, this is the most important thing. It's the definition of prime factors.3. After the division by 5, you have an answer left over, the quotient. Now you need to factor that quotient, if it is not already prime, by going to back to step one and using a trial division.4. Repeat 1-3 until you cant divide the answers further, and all you have left are prime numbers. When you multiply these numbers together, you will get 185 if you did everything correctly.HINT: 185 has only 2 prime factors, 5 and 37Prime factors of 185 are 5 and 37

This is a homework question. I won't answer it directly, but I'll ask you some questions that lead you to the answer. First, divide 30030 by 30 (why? because it looks like the larger number is divisible by 30). Does it divide evenly? If the answer is yes, both the answer and 30 are factors. Use trial division to identify the prime factors of 30 and the answer to the above division, assuming the result was not a decimal. Hint: there are six prime factors of 30030, and this particular group of prime factors is very special. These factors are the six _____ contiguous prime numbers. I found the answer in just a couple of minutes, using only paper and pencil.

Yes.
11 is a prime number therefore the only number that factors 11 is 1 and itself
2 x 32 = 18
