To determine if 847 is a prime number or a composite number, we simply look at the factors for 847.
If the factors of 847 are only 847 and 1, then we know that 847 is a prime number. Otherwise, 847 is a composite number.
To explain better, if 847 is only divisible by 1 and 847, then it is a prime number, and if 847 is divisible by more than 847 and 1, then it is a composite number.
The factors of 847 are as follows:
1, 7, 11, 77, 121, 847
Therefore, since 847 is divisible by more than one and itself, the answer to the
question "Is 847 prime or composite?" is highlighted in blue below.
composite
Is 848 prime or composite?
