To determine if 6345 is a prime number or a composite number, we simply look at the factors for 6345.
If the factors of 6345 are only 6345 and 1, then we know that 6345 is a prime number. Otherwise, 6345 is a composite number.
To explain better, if 6345 is only divisible by 1 and 6345, then it is a prime number, and if 6345 is divisible by more than 6345 and 1, then it is a composite number.
The factors of 6345 are as follows:
1, 3, 5, 9, 15, 27, 45, 47, 135, 141, 235, 423, 705, 1269, 2115, 6345
Therefore, since 6345 is divisible by more than one and itself, the answer to the
question "Is 6345 prime or composite?" is highlighted in blue below.
