To determine if 49 is a prime number or a composite number, we simply look at the factors for 49.
If the factors of 49 are only 49 and 1, then we know that 49 is a prime number. Otherwise, 49 is a composite number.
To explain better, if 49 is only divisible by 1 and 49, then it is a prime number, and if 49 is divisible by more than 49 and 1, then it is a composite number.
The factors of 49 are as follows:
1, 7, 49
Therefore, since 49 is divisible by more than one and itself, the answer to the
question "Is 49 prime or composite?" is highlighted in blue below.
composite
Is 50 prime or composite?
OK. Now you know that 49 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.
