Prime Number

Prime Number
A whole number that can not be made by multiplying other whole numbers.

Example: 5 is a prime number. We cannot multiply 2, 3 or 4 together to make 5. (Only 1×5 works but we said to use other whole numbers.)

Example: 6 can be made by 2 × 3 so is NOT a prime number (it is a composite number).
