The number 1 is the smallest factor of every number. Every number will have a minimum of two factors, 1 and the number itself. A number that has only two factors, 1 and the number itself, is called a prime number.
What type of number is 1?
): The counting numbers {1, 2, 3.} are commonly called natural numbers; however, other definitions include 0, so that the non-negative integers {0, 1, 2, 3.} are also called natural numbers. Natural numbers including 0 are also called whole numbers.
Is 0.5 a natural number?

Which is the easiest way to factor a number?
Write the prime factor in the left column and write your answer across from it in the right column. As noted above, even numbers are especially easy to start factoring because their smallest prime factor will always be 2. Odd numbers, on the other hand, will have smallest prime factors that differ.
