To determine if 7854 is a prime number or a composite number, we simply look at the factors for 7854.
If the factors of 7854 are only 7854 and 1, then we know that 7854 is a prime number. Otherwise, 7854 is a composite number.
To explain better, if 7854 is only divisible by 1 and 7854, then it is a prime number, and if 7854 is divisible by more than 7854 and 1, then it is a composite number.
The factors of 7854 are as follows:
1, 2, 3, 6, 7, 11, 14, 17, 21, 22, 33, 34, 42, 51, 66, 77, 102, 119, 154, 187, 231, 238, 357, 374, 462, 561, 714, 1122, 1309, 2618, 3927, 7854
Therefore, since 7854 is divisible by more than one and itself, the answer to the
question "Is 7854 prime or composite?" is highlighted in blue below.
