To determine if 862 is a prime number or a composite number, we simply look at the factors for 862.
If the factors of 862 are only 862 and 1, then we know that 862 is a prime number. Otherwise, 862 is a composite number.
To explain better, if 862 is only divisible by 1 and 862, then it is a prime number, and if 862 is divisible by more than 862 and 1, then it is a composite number.
The factors of 862 are as follows:
1, 2, 431, 862
Therefore, since 862 is divisible by more than one and itself, the answer to the
question "Is 862 prime or composite?" is highlighted in blue below.
composite
Is 863 prime or composite?
OK. Now you know that 862 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.
