To determine if 854 is a prime number or a composite number, we simply look at the factors for 854.
If the factors of 854 are only 854 and 1, then we know that 854 is a prime number. Otherwise, 854 is a composite number.
To explain better, if 854 is only divisible by 1 and 854, then it is a prime number, and if 854 is divisible by more than 854 and 1, then it is a composite number.
The factors of 854 are as follows:
1, 2, 7, 14, 61, 122, 427, 854
Therefore, since 854 is divisible by more than one and itself, the answer to the
question "Is 854 prime or composite?" is highlighted in blue below.
composite
