To determine if 7210 is a prime number or a composite number, we simply look at the factors for 7210.
If the factors of 7210 are only 7210 and 1, then we know that 7210 is a prime number. Otherwise, 7210 is a composite number.
To explain better, if 7210 is only divisible by 1 and 7210, then it is a prime number, and if 7210 is divisible by more than 7210 and 1, then it is a composite number.
The factors of 7210 are as follows:
1, 2, 5, 7, 10, 14, 35, 70, 103, 206, 515, 721, 1030, 1442, 3605, 7210
Therefore, since 7210 is divisible by more than one and itself, the answer to the
question "Is 7210 prime or composite?" is highlighted in blue below.
composite
Is 7211 prime or composite?
