Is 129 a prime or composite number?
Question:
Is 129 a prime or composite number?
Factors:
All whole numbers have at least two factors: the number itself and 1. For example, the number 17 has the factors 1 and 17. A number that is greater than one and has just two factors is a prime number. If the number has more than two factors it is a composite number. For example, the number 6 has the factors 1, 2, 3, and 6, so it is a composite number.
