To determine if 6140 is a prime number or a composite number, we simply look at the factors for 6140.
If the factors of 6140 are only 6140 and 1, then we know that 6140 is a prime number. Otherwise, 6140 is a composite number.
To explain better, if 6140 is only divisible by 1 and 6140, then it is a prime number, and if 6140 is divisible by more than 6140 and 1, then it is a composite number.
The factors of 6140 are as follows:
1, 2, 4, 5, 10, 20, 307, 614, 1228, 1535, 3070, 6140
Therefore, since 6140 is divisible by more than one and itself, the answer to the
question "Is 6140 prime or composite?" is highlighted in blue below.
composite
Is 6141 prime or composite?
