A prime number has exactly two factors, 1 and the number itself. A composite number has more factors than 1 and itself.
Is ninety-seven a prime number?
97 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are every other positive integer except 1 and 0. 1 and 0 are neither prime, nor composite.
Is the number 1 a prime or composite?
The concept of prime or composite is defined only for integers greater than 1.
An alternative argument that is that a 1 has only 1 factor, which is 1. Primes have exactly 2, and composites more than 2. So 1 is neither prime nor composite.
This ensures that the unique prime factorisation theorem (the fundamental theorem of arithmetic) is true.
Is 62 prime or composite or neither?
Composite. All positive, whole numbers greater than two and ending in 0, 2, 4, 6 or 8 are composite.
3455 is composite: its prime factorisation is 5 x 691.
What is a good question for the numbers 16 17 20 22 25 and 30 in third grade level?

Why can you not make a sudoku puzzle with all prime numbers?
I am assuming you are referring to a normal 3x3 sudoku grid, where you can only use the numbers 1-9 once in the grid, and by prime number you mean the 3digit number across and down the grid must be prime? For a number to be prime, it must end in 1, 3, 7 or 9. There are 5 places on the Sudoku grid for a number to finish and as you can only use a number once in sudoku you have one place left where the number can not be prime. This means the most you can have is 5 prime numbers.
What is a prime number and what is a composite number?
A prime number is a number which has no factors except 1 and itself. For example: 107 is prime because its factors are 1 and 107.
A composite number is a number which has more that 1 and itself for factors. For example: 14 is composite because its factors are 1, 2, 7, and 14.
