To determine if 1964 is a prime number or a composite number, we simply look at the factors for 1964.
If the factors of 1964 are only 1964 and 1, then we know that 1964 is a prime number. Otherwise, 1964 is a composite number.
To explain better, if 1964 is only divisible by 1 and 1964, then it is a prime number, and if 1964 is divisible by more than 1964 and 1, then it is a composite number.
The factors of 1964 are as follows:
1, 2, 4, 491, 982, 1964
Therefore, since 1964 is divisible by more than one and itself, the answer to the
question "Is 1964 prime or composite?" is highlighted in blue below.
composite
Is 1965 prime or composite?
