To determine if 7784 is a prime number or a composite number, we simply look at the factors for 7784.
If the factors of 7784 are only 7784 and 1, then we know that 7784 is a prime number. Otherwise, 7784 is a composite number.
To explain better, if 7784 is only divisible by 1 and 7784, then it is a prime number, and if 7784 is divisible by more than 7784 and 1, then it is a composite number.
The factors of 7784 are as follows:
1, 2, 4, 7, 8, 14, 28, 56, 139, 278, 556, 973, 1112, 1946, 3892, 7784
Therefore, since 7784 is divisible by more than one and itself, the answer to the
question "Is 7784 prime or composite?" is highlighted in blue below.
