To determine if 7000 is a prime number or a composite number, we simply look at the factors for 7000.
If the factors of 7000 are only 7000 and 1, then we know that 7000 is a prime number. Otherwise, 7000 is a composite number.
To explain better, if 7000 is only divisible by 1 and 7000, then it is a prime number, and if 7000 is divisible by more than 7000 and 1, then it is a composite number.
The factors of 7000 are as follows:
1, 2, 4, 5, 7, 8, 10, 14, 20, 25, 28, 35, 40, 50, 56, 70, 100, 125, 140, 175, 200, 250, 280, 350, 500, 700, 875, 1000, 1400, 1750, 3500, 7000
Therefore, since 7000 is divisible by more than one and itself, the answer to the
question "Is 7000 prime or composite?" is highlighted in blue below.
composite
Is 7001 prime or composite?
OK. Now you know that 7000 is a composite number. Use our logic above and see if
you can figure out if the next number on our list is prime or composite before you check your answer.
