To determine if 1415 is a prime number or a composite number, we simply look at the factors for 1415.
If the factors of 1415 are only 1415 and 1, then we know that 1415 is a prime number. Otherwise, 1415 is a composite number.
To explain better, if 1415 is only divisible by 1 and 1415, then it is a prime number, and if 1415 is divisible by more than 1415 and 1, then it is a composite number.
The factors of 1415 are as follows:
1, 5, 283, 1415
Therefore, since 1415 is divisible by more than one and itself, the answer to the
question "Is 1415 prime or composite?" is highlighted in blue below.
composite
Is 1416 prime or composite?
