To determine if 3430 is a prime number or a composite number, we simply look at the factors for 3430.
If the factors of 3430 are only 3430 and 1, then we know that 3430 is a prime number. Otherwise, 3430 is a composite number.
To explain better, if 3430 is only divisible by 1 and 3430, then it is a prime number, and if 3430 is divisible by more than 3430 and 1, then it is a composite number.
The factors of 3430 are as follows:
1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 343, 490, 686, 1715, 3430
Therefore, since 3430 is divisible by more than one and itself, the answer to the
question "Is 3430 prime or composite?" is highlighted in blue below.
composite
Is 3431 prime or composite?
