To determine if 3530 is a prime number or a composite number, we simply look at the factors for 3530.
If the factors of 3530 are only 3530 and 1, then we know that 3530 is a prime number. Otherwise, 3530 is a composite number.
To explain better, if 3530 is only divisible by 1 and 3530, then it is a prime number, and if 3530 is divisible by more than 3530 and 1, then it is a composite number.
The factors of 3530 are as follows:
1, 2, 5, 10, 353, 706, 1765, 3530
Therefore, since 3530 is divisible by more than one and itself, the answer to the
question "Is 3530 prime or composite?" is highlighted in blue below.
