To determine if 1235 is a prime number or a composite number, we simply look at the factors for 1235.
If the factors of 1235 are only 1235 and 1, then we know that 1235 is a prime number. Otherwise, 1235 is a composite number.
To explain better, if 1235 is only divisible by 1 and 1235, then it is a prime number, and if 1235 is divisible by more than 1235 and 1, then it is a composite number.
The factors of 1235 are as follows:
1, 5, 13, 19, 65, 95, 247, 1235
Therefore, since 1235 is divisible by more than one and itself, the answer to the
question "Is 1235 prime or composite?" is highlighted in blue below.
composite
Is 1236 prime or composite?
