To determine if 3690 is a prime number or a composite number, we simply look at the factors for 3690.
If the factors of 3690 are only 3690 and 1, then we know that 3690 is a prime number. Otherwise, 3690 is a composite number.
To explain better, if 3690 is only divisible by 1 and 3690, then it is a prime number, and if 3690 is divisible by more than 3690 and 1, then it is a composite number.
The factors of 3690 are as follows:
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 41, 45, 82, 90, 123, 205, 246, 369, 410, 615, 738, 1230, 1845, 3690
Therefore, since 3690 is divisible by more than one and itself, the answer to the
question "Is 3690 prime or composite?" is highlighted in blue below.
