To determine if 7100 is a prime number or a composite number, we simply look at the factors for 7100.
If the factors of 7100 are only 7100 and 1, then we know that 7100 is a prime number. Otherwise, 7100 is a composite number.
To explain better, if 7100 is only divisible by 1 and 7100, then it is a prime number, and if 7100 is divisible by more than 7100 and 1, then it is a composite number.
The factors of 7100 are as follows:
1, 2, 4, 5, 10, 20, 25, 50, 71, 100, 142, 284, 355, 710, 1420, 1775, 3550, 7100
Therefore, since 7100 is divisible by more than one and itself, the answer to the
question "Is 7100 prime or composite?" is highlighted in blue below.
composite
Is 7101 prime or composite?
