To determine if 1210 is a prime number or a composite number, we simply look at the factors for 1210.
If the factors of 1210 are only 1210 and 1, then we know that 1210 is a prime number. Otherwise, 1210 is a composite number.
To explain better, if 1210 is only divisible by 1 and 1210, then it is a prime number, and if 1210 is divisible by more than 1210 and 1, then it is a composite number.
The factors of 1210 are as follows:
1, 2, 5, 10, 11, 22, 55, 110, 121, 242, 605, 1210
Therefore, since 1210 is divisible by more than one and itself, the answer to the
question "Is 1210 prime or composite?" is highlighted in blue below.
composite
Is 1211 prime or composite?
