To determine if 1127 is a prime number or a composite number, we simply look at the factors for 1127.
If the factors of 1127 are only 1127 and 1, then we know that 1127 is a prime number. Otherwise, 1127 is a composite number.
To explain better, if 1127 is only divisible by 1 and 1127, then it is a prime number, and if 1127 is divisible by more than 1127 and 1, then it is a composite number.
The factors of 1127 are as follows:
1, 7, 23, 49, 161, 1127
Therefore, since 1127 is divisible by more than one and itself, the answer to the
question "Is 1127 prime or composite?" is highlighted in blue below.
