To determine if 1310 is a prime number or a composite number, we simply look at the factors for 1310.
If the factors of 1310 are only 1310 and 1, then we know that 1310 is a prime number. Otherwise, 1310 is a composite number.
To explain better, if 1310 is only divisible by 1 and 1310, then it is a prime number, and if 1310 is divisible by more than 1310 and 1, then it is a composite number.
The factors of 1310 are as follows:
1, 2, 5, 10, 131, 262, 655, 1310
Therefore, since 1310 is divisible by more than one and itself, the answer to the
question "Is 1310 prime or composite?" is highlighted in blue below.
composite
Is 1311 prime or composite?
