What is the definition of prime composite?

A prime number is a natural number that has exactly two distinct natural number divisors: 1 and itself.

A composite number is a positive integer which has a positive divisor other than one or itself.

Is 9 a prime or composite number?

A prime number is not divisible by any numbers except 1 and itself. A composite number is divisible by other numbers. 9 is divisible by 3, so it is a composite number.

Is 41 composite or prime?

The number 41 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

To test a number to find out if it is prime or composite, try dividing it by the first few prime numbers:

  • 41 ÷ 2 = 20 r 1
  • 41 ÷ 3 = 13 r 2
  • 41 ÷ 5 = 8 r 1
  • 41 ÷ 7 = 5 r 6
We don't have to test 4 or 6, since they are both divisible by 2. The divisor (7) is now larger than the result (5 remainder 6), so we can stop. 41 is prime.

What are the first 10 composite numbers?

The first 10 composites are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18.
