To determine if 61 is a prime number or a composite number, we simply look at the factors for 61.
If the factors of 61 are only 61 and 1, then we know that 61 is a prime number. Otherwise, 61 is a composite number.
To explain better, if 61 is only divisible by 1 and 61, then it is a prime number, and if 61 is divisible by more than 61 and 1, then it is a composite number.
The factors of 61 are as follows:
1, 61
Therefore, since 61 is divisible by only one and itself, the answer to the
question "Is 61 prime or composite?" is highlighted in blue below.
prime
Is 62 prime or composite?
OK. Now you know that 61 is a prime 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.
