To determine if 5215 is a prime number or a composite number, we simply look at the factors for 5215.
If the factors of 5215 are only 5215 and 1, then we know that 5215 is a prime number. Otherwise, 5215 is a composite number.
To explain better, if 5215 is only divisible by 1 and 5215, then it is a prime number, and if 5215 is divisible by more than 5215 and 1, then it is a composite number.
The factors of 5215 are as follows:
1, 5, 7, 35, 149, 745, 1043, 5215
Therefore, since 5215 is divisible by more than one and itself, the answer to the
question "Is 5215 prime or composite?" is highlighted in blue below.
