To determine if 1954 is a prime number or a composite number, we simply look at the factors for 1954.
If the factors of 1954 are only 1954 and 1, then we know that 1954 is a prime number. Otherwise, 1954 is a composite number.
To explain better, if 1954 is only divisible by 1 and 1954, then it is a prime number, and if 1954 is divisible by more than 1954 and 1, then it is a composite number.
The factors of 1954 are as follows:
1, 2, 977, 1954
Therefore, since 1954 is divisible by more than one and itself, the answer to the
question "Is 1954 prime or composite?" is highlighted in blue below.
