First you have to break down the 18
18
/ \
3x6 {3 times 6 is 18}
__/ \ {break down the 6}
2x3 {2 times 3 is 6}
The numbers that you cannot break it down its the prime number.
18
/ \
*3x6
___/ \
__*2x*3
Answer: 2x3x3 Or 2 times 3 squared
To check the answer, multiply these factors and make sure they equal 18.

if that is too confusing then look at this:
18 ÷ 2 = 9
9 ÷ 3 =3 prime number
18 ÷ *2 = 9
9 ÷ *3 =*3
prime factors = 2×3x3
To check the answer, multiply these factors and make sure they equal 18.
I hope this help and not too confusing ^_^

To find the prime factor, first divide the number by the smallest possible prime (2). This factorization becomes
2 x 9
Then nine can be divided by the next smallest prime (3). Then the factorization becomes
2 x 3 x 3
The last quotient is a prime number (3), and so this is the prime factorization of 18.

18 divided by 6 is 3. 2 times 3 is 6. 2 x 2 x 3. they're all prime, and when multiplied together, they equal 18.

18=9x2
Because 9 is not prime, we need to prime factorize it too.
9x2=3x3
3x3x2=18
3x3x2 is your answer.
