To determine if 7281 is a prime number or a composite number, we simply look at the factors for 7281.
If the factors of 7281 are only 7281 and 1, then we know that 7281 is a prime number. Otherwise, 7281 is a composite number.
To explain better, if 7281 is only divisible by 1 and 7281, then it is a prime number, and if 7281 is divisible by more than 7281 and 1, then it is a composite number.
The factors of 7281 are as follows:
1, 3, 9, 809, 2427, 7281
Therefore, since 7281 is divisible by more than one and itself, the answer to the
question "Is 7281 prime or composite?" is highlighted in blue below.
