To determine if 6490 is a prime number or a composite number, we simply look at the factors for 6490.
If the factors of 6490 are only 6490 and 1, then we know that 6490 is a prime number. Otherwise, 6490 is a composite number.
To explain better, if 6490 is only divisible by 1 and 6490, then it is a prime number, and if 6490 is divisible by more than 6490 and 1, then it is a composite number.
The factors of 6490 are as follows:
1, 2, 5, 10, 11, 22, 55, 59, 110, 118, 295, 590, 649, 1298, 3245, 6490
Therefore, since 6490 is divisible by more than one and itself, the answer to the
question "Is 6490 prime or composite?" is highlighted in blue below.
