To determine if 8490 is a prime number or a composite number, we simply look at the factors for 8490.
If the factors of 8490 are only 8490 and 1, then we know that 8490 is a prime number. Otherwise, 8490 is a composite number.
To explain better, if 8490 is only divisible by 1 and 8490, then it is a prime number, and if 8490 is divisible by more than 8490 and 1, then it is a composite number.
The factors of 8490 are as follows:
1, 2, 3, 5, 6, 10, 15, 30, 283, 566, 849, 1415, 1698, 2830, 4245, 8490
Therefore, since 8490 is divisible by more than one and itself, the answer to the
question "Is 8490 prime or composite?" is highlighted in blue below.
