To determine if 7686 is a prime number or a composite number, we simply look at the factors for 7686.
If the factors of 7686 are only 7686 and 1, then we know that 7686 is a prime number. Otherwise, 7686 is a composite number.
To explain better, if 7686 is only divisible by 1 and 7686, then it is a prime number, and if 7686 is divisible by more than 7686 and 1, then it is a composite number.
The factors of 7686 are as follows:
1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 61, 63, 122, 126, 183, 366, 427, 549, 854, 1098, 1281, 2562, 3843, 7686
Therefore, since 7686 is divisible by more than one and itself, the answer to the
question "Is 7686 prime or composite?" is highlighted in blue below.
