To determine if 7826 is a prime number or a composite number, we simply look at the factors for 7826.
If the factors of 7826 are only 7826 and 1, then we know that 7826 is a prime number. Otherwise, 7826 is a composite number.
To explain better, if 7826 is only divisible by 1 and 7826, then it is a prime number, and if 7826 is divisible by more than 7826 and 1, then it is a composite number.
The factors of 7826 are as follows:
1, 2, 7, 13, 14, 26, 43, 86, 91, 182, 301, 559, 602, 1118, 3913, 7826
Therefore, since 7826 is divisible by more than one and itself, the answer to the
question "Is 7826 prime or composite?" is highlighted in blue below.
