To determine if 1261 is a prime number or a composite number, we simply look at the factors for 1261.
If the factors of 1261 are only 1261 and 1, then we know that 1261 is a prime number. Otherwise, 1261 is a composite number.
To explain better, if 1261 is only divisible by 1 and 1261, then it is a prime number, and if 1261 is divisible by more than 1261 and 1, then it is a composite number.
The factors of 1261 are as follows:
1, 13, 97, 1261
Therefore, since 1261 is divisible by more than one and itself, the answer to the
question "Is 1261 prime or composite?" is highlighted in blue below.
composite
Is 1262 prime or composite?
OK. Now you know that 1261 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
