To determine if 1966 is a prime number or a composite number, we simply look at the factors for 1966.
If the factors of 1966 are only 1966 and 1, then we know that 1966 is a prime number. Otherwise, 1966 is a composite number.
To explain better, if 1966 is only divisible by 1 and 1966, then it is a prime number, and if 1966 is divisible by more than 1966 and 1, then it is a composite number.
The factors of 1966 are as follows:
1, 2, 983, 1966
Therefore, since 1966 is divisible by more than one and itself, the answer to the
question "Is 1966 prime or composite?" is highlighted in blue below.
