To determine if 1246 is a prime number or a composite number, we simply look at the factors for 1246.
If the factors of 1246 are only 1246 and 1, then we know that 1246 is a prime number. Otherwise, 1246 is a composite number.
To explain better, if 1246 is only divisible by 1 and 1246, then it is a prime number, and if 1246 is divisible by more than 1246 and 1, then it is a composite number.
The factors of 1246 are as follows:
1, 2, 7, 14, 89, 178, 623, 1246
Therefore, since 1246 is divisible by more than one and itself, the answer to the
question "Is 1246 prime or composite?" is highlighted in blue below.
composite
Is 1247 prime or composite?
