To determine if 2458 is a prime number or a composite number, we simply look at the factors for 2458.
If the factors of 2458 are only 2458 and 1, then we know that 2458 is a prime number. Otherwise, 2458 is a composite number.
To explain better, if 2458 is only divisible by 1 and 2458, then it is a prime number, and if 2458 is divisible by more than 2458 and 1, then it is a composite number.
The factors of 2458 are as follows:
