To determine if 2553 is a prime number or a composite number, we simply look at the factors for 2553.
If the factors of 2553 are only 2553 and 1, then we know that 2553 is a prime number. Otherwise, 2553 is a composite number.
To explain better, if 2553 is only divisible by 1 and 2553, then it is a prime number, and if 2553 is divisible by more than 2553 and 1, then it is a composite number.
The factors of 2553 are as follows:
1, 3, 23, 37, 69, 111, 851, 2553
Therefore, since 2553 is divisible by more than one and itself, the answer to the
question "Is 2553 prime or composite?" is highlighted in blue below.
