To determine if 7850 is a prime number or a composite number, we simply look at the factors for 7850.
If the factors of 7850 are only 7850 and 1, then we know that 7850 is a prime number. Otherwise, 7850 is a composite number.
To explain better, if 7850 is only divisible by 1 and 7850, then it is a prime number, and if 7850 is divisible by more than 7850 and 1, then it is a composite number.
The factors of 7850 are as follows:
1, 2, 5, 10, 25, 50, 157, 314, 785, 1570, 3925, 7850
Therefore, since 7850 is divisible by more than one and itself, the answer to the
question "Is 7850 prime or composite?" is highlighted in blue below.
composite
Is 7851 prime or composite?
