To determine if 8340 is a prime number or a composite number, we simply look at the factors for 8340.
If the factors of 8340 are only 8340 and 1, then we know that 8340 is a prime number. Otherwise, 8340 is a composite number.
To explain better, if 8340 is only divisible by 1 and 8340, then it is a prime number, and if 8340 is divisible by more than 8340 and 1, then it is a composite number.
The factors of 8340 are as follows:
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60, 139, 278, 417, 556, 695, 834, 1390, 1668, 2085, 2780, 4170, 8340
Therefore, since 8340 is divisible by more than one and itself, the answer to the
question "Is 8340 prime or composite?" is highlighted in blue below.
composite
Is 8341 prime or composite?
