To determine if 1204 is a prime number or a composite number, we simply look at the factors for 1204.
If the factors of 1204 are only 1204 and 1, then we know that 1204 is a prime number. Otherwise, 1204 is a composite number.
To explain better, if 1204 is only divisible by 1 and 1204, then it is a prime number, and if 1204 is divisible by more than 1204 and 1, then it is a composite number.
The factors of 1204 are as follows:
1, 2, 4, 7, 14, 28, 43, 86, 172, 301, 602, 1204
Therefore, since 1204 is divisible by more than one and itself, the answer to the
question "Is 1204 prime or composite?" is highlighted in blue below.
composite
