To determine if 1654 is a prime number or a composite number, we simply look at the factors for 1654.
If the factors of 1654 are only 1654 and 1, then we know that 1654 is a prime number. Otherwise, 1654 is a composite number.
To explain better, if 1654 is only divisible by 1 and 1654, then it is a prime number, and if 1654 is divisible by more than 1654 and 1, then it is a composite number.
The factors of 1654 are as follows:
1, 2, 827, 1654
Therefore, since 1654 is divisible by more than one and itself, the answer to the
question "Is 1654 prime or composite?" is highlighted in blue below.
