To determine if 4990 is a prime number or a composite number, we simply look at the factors for 4990.
If the factors of 4990 are only 4990 and 1, then we know that 4990 is a prime number. Otherwise, 4990 is a composite number.
To explain better, if 4990 is only divisible by 1 and 4990, then it is a prime number, and if 4990 is divisible by more than 4990 and 1, then it is a composite number.
The factors of 4990 are as follows:
1, 2, 5, 10, 499, 998, 2495, 4990
