To determine if 8450 is a prime number or a composite number, we simply look at the factors for 8450.
If the factors of 8450 are only 8450 and 1, then we know that 8450 is a prime number. Otherwise, 8450 is a composite number.
To explain better, if 8450 is only divisible by 1 and 8450, then it is a prime number, and if 8450 is divisible by more than 8450 and 1, then it is a composite number.
The factors of 8450 are as follows:
1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 169, 325, 338, 650, 845, 1690, 4225, 8450
Therefore, since 8450 is divisible by more than one and itself, the answer to the
question "Is 8450 prime or composite?" is highlighted in blue below.
composite
Is 8451 prime or composite?
