To determine if 1513 is a prime number or a composite number, we simply look at the factors for 1513.
If the factors of 1513 are only 1513 and 1, then we know that 1513 is a prime number. Otherwise, 1513 is a composite number.
To explain better, if 1513 is only divisible by 1 and 1513, then it is a prime number, and if 1513 is divisible by more than 1513 and 1, then it is a composite number.
The factors of 1513 are as follows:
1, 17, 89, 1513
Therefore, since 1513 is divisible by more than one and itself, the answer to the
question "Is 1513 prime or composite?" is highlighted in blue below.
composite
Is 1514 prime or composite?
