To determine if 3450 is a prime number or a composite number, we simply look at the factors for 3450.
If the factors of 3450 are only 3450 and 1, then we know that 3450 is a prime number. Otherwise, 3450 is a composite number.
To explain better, if 3450 is only divisible by 1 and 3450, then it is a prime number, and if 3450 is divisible by more than 3450 and 1, then it is a composite number.
The factors of 3450 are as follows:
1, 2, 3, 5, 6, 10, 15, 23, 25, 30, 46, 50, 69, 75, 115, 138, 150, 230, 345, 575, 690, 1150, 1725, 3450
Therefore, since 3450 is divisible by more than one and itself, the answer to the
question "Is 3450 prime or composite?" is highlighted in blue below.
composite
