To determine if 7105 is a prime number or a composite number, we simply look at the factors for 7105.
If the factors of 7105 are only 7105 and 1, then we know that 7105 is a prime number. Otherwise, 7105 is a composite number.
To explain better, if 7105 is only divisible by 1 and 7105, then it is a prime number, and if 7105 is divisible by more than 7105 and 1, then it is a composite number.
The factors of 7105 are as follows:
1, 5, 7, 29, 35, 49, 145, 203, 245, 1015, 1421, 7105
Therefore, since 7105 is divisible by more than one and itself, the answer to the
question "Is 7105 prime or composite?" is highlighted in blue below.
composite
