To determine if 7776 is a prime number or a composite number, we simply look at the factors for 7776.
If the factors of 7776 are only 7776 and 1, then we know that 7776 is a prime number. Otherwise, 7776 is a composite number.
To explain better, if 7776 is only divisible by 1 and 7776, then it is a prime number, and if 7776 is divisible by more than 7776 and 1, then it is a composite number.
The factors of 7776 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 81, 96, 108, 144, 162, 216, 243, 288, 324, 432, 486, 648, 864, 972, 1296, 1944, 2592, 3888, 7776
Therefore, since 7776 is divisible by more than one and itself, the answer to the
question "Is 7776 prime or composite?" is highlighted in blue below.
