To determine if 3185 is a prime number or a composite number, we simply look at the factors for 3185.
If the factors of 3185 are only 3185 and 1, then we know that 3185 is a prime number. Otherwise, 3185 is a composite number.
To explain better, if 3185 is only divisible by 1 and 3185, then it is a prime number, and if 3185 is divisible by more than 3185 and 1, then it is a composite number.
The factors of 3185 are as follows:
1, 5, 7, 13, 35, 49, 65, 91, 245, 455, 637, 3185
Therefore, since 3185 is divisible by more than one and itself, the answer to the
question "Is 3185 prime or composite?" is highlighted in blue below.
