To determine if 1946 is a prime number or a composite number, we simply look at the factors for 1946.
If the factors of 1946 are only 1946 and 1, then we know that 1946 is a prime number. Otherwise, 1946 is a composite number.
To explain better, if 1946 is only divisible by 1 and 1946, then it is a prime number, and if 1946 is divisible by more than 1946 and 1, then it is a composite number.
The factors of 1946 are as follows:
1, 2, 7, 14, 139, 278, 973, 1946
Therefore, since 1946 is divisible by more than one and itself, the answer to the
question "Is 1946 prime or composite?" is highlighted in blue below.
