A Prime Number can be divided evenly only by 1 or itself. And it must be a whole number greater than 1.Prime Number
"Factors" are the numbers you multiply together to get another number: 2 X 3 = 6 2 AND 3 ARE FACTORS
"Prime Factorization" is finding which prime numbers multiply together to make the original number.
It is best to start working from the smallest prime number, which is 2, so let's check: 12 ÷ 2 = 6
Yes, it divided evenly by 2. We have taken the first step! But 6 is not a prime number, so we need to go further. Let's try 2 again: 6 ÷ 2 = 3
Yes, that worked also. And 3 is a prime number, so we have the answer: 12 = 2 × 2 × 3
As you can see, every factor is a prime number, so the answer must be right.
Can we divide 147 evenly by 2? No, so we should try the next prime number, 3: 147 ÷ 3 = 49
Then we try factoring 49, and find that 7 is the smallest prime number that works: 49 ÷ 7 = 7
And that is as far as we need to go, because all the factors are prime numbers. 147 = 3 × 7 × 7
We showed you how to do the factorization by starting at the smallest prime and working upwards.
But sometimes it is easier to break a number down into any factors you can... then work those factor down to primes.
Break 90 into 9 × 10 The prime factors of 9 are 3 and 3 The prime factors of 10 are 2 and 5
So the prime factors of 90 are 3, 3, 2 and 5
There is only one (unique!) set of prime factors for any number.
330 = 2 × 3 × 5 × 11 There is no other possible set of prime numbers that can be multiplied to make 330.
