We know that 143 is a whole number and that it has to be either prime or composite because all whole numbers other than 0 and 1 are one or the other. So, in order to determine if it is prime or composite, we need to know if any numbers besides 1 and 143 are factors. 1, 11, 13, and 143 are factors so 143 is a composite number.

143 is composite.

11 x 13 = 143, making it composite.

143 is not prime. 143 = 11 * 13

Composite.

143 is divisible by 11.

The numbers 2, 13, and 43 are prime. 143 is a composite number. Its positive integer factors, other than one and itself, are 11 and 13.

No. Prime numbers cannot be composite and composite numbers cannot be prime!

The only composite factor of 143 is 143.

Prime factorization never includes a composite number. All numbers in prime factorization must be prime numbers.

no. There is a prime number and a composite number. Therefor, all prime numbers are not composite.

No, prime factorizations consist entirely of prime numbers.

No, there are more composite numbers than prime numbers.

143 is a composite number because it has more than two factors

The product of two prime numbers will be composite.

Numbers other than prime prime numbers are composite numbers. Only whole numbers should be considered for prime & composite numbers. However, '1' is an exceptional case because it is neither prime nor composite.

Prime numbers are not composite.

Prime numbers have two factors, composite numbers have more than two.

The 'opposite' status of a number that is not prime is a composite number.Except for 0 and 1, all numbers that are not prime (i.e. they are multiples of other numbers) are called composite numbers.The opposite of a prime number would be a number that is not prime. Almost all numbers that are not prime are composite numbers. A prime number is a number that has exactly two factors. A composite number has more than two factors. However, composite numbers do not include all numbers that are not prime. The number 1 has only one factor, so it is neither prime nor composite - it is unity.

The relationship between prime numbers and composite numbers is that they are antonyms or opposites of each other. A natural number, is either prime or composite, but it can not be both. Prime numbers have only two factors, one and itself. Composite numbers are whole numbers that are not prime numbers, which means that they have factors other than one and itself.

It is impossible to list the infinite number of prime numbers and composite numbers.

what is the ratio or prime numbers to composite numbers in this list/10,11,2,13,14,15,16,1,7,18,19,20,21

Yes, there are many more composite numbers than prime.

Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.

There are more composite numbers than prime numbers, but there is no prime or composite number so great that you can't find a greater one of either kind.
