To determine if 1969 is a prime number or a composite number, we simply look at the factors for 1969.
If the factors of 1969 are only 1969 and 1, then we know that 1969 is a prime number. Otherwise, 1969 is a composite number.
To explain better, if 1969 is only divisible by 1 and 1969, then it is a prime number, and if 1969 is divisible by more than 1969 and 1, then it is a composite number.
The factors of 1969 are as follows:
