To determine if 669 is a prime number or a composite number, we simply look at the factors for 669.
If the factors of 669 are only 669 and 1, then we know that 669 is a prime number. Otherwise, 669 is a composite number.
To explain better, if 669 is only divisible by 1 and 669, then it is a prime number, and if 669 is divisible by more than 669 and 1, then it is a composite number.
The factors of 669 are as follows:
1, 3, 223, 669
Therefore, since 669 is divisible by more than one and itself, the answer to the
question "Is 669 prime or composite?" is highlighted in blue below.
