List all the factors and the first four multiples of 30. Cross out 0 and 1 (neither prime nor composite) and circle 2 (the first prime) Circle 3 (prime) and cross out all multiples of 3. Categorize the following as Prime, Composite or Neither: 0, 1, 2, and any negative number

The circled numbers multiplied together create the prime factorization of the given number. Recall that order doesn't matter when we multiply (multiplication is commutative; 3*2 = 2*3), so this theorem says if we order the prime factors from smallest to largest, everyone will get the same answer of prime factors for a given number.

Any natural number (positive integer), which has a positive integer factor other than 1 and itself is called a composite number.
