To determine if 7150 is a prime number or a composite number, we simply look at the factors for 7150.
If the factors of 7150 are only 7150 and 1, then we know that 7150 is a prime number. Otherwise, 7150 is a composite number.
To explain better, if 7150 is only divisible by 1 and 7150, then it is a prime number, and if 7150 is divisible by more than 7150 and 1, then it is a composite number.
The factors of 7150 are as follows:
1, 2, 5, 10, 11, 13, 22, 25, 26, 50, 55, 65, 110, 130, 143, 275, 286, 325, 550, 650, 715, 1430, 3575, 7150
Therefore, since 7150 is divisible by more than one and itself, the answer to the
question "Is 7150 prime or composite?" is highlighted in blue below.
composite
Is 7151 prime or composite?
