Composite Numbers

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30 are all the composite numbers below 30.

The number 67 is a prime number as it can only be divided by itself and one

Composite numbers are the non-prime numbers, numbers that have more than two factors. Every number that is not prime (has factors other than one and itself) is a composite number. A composite number is divisible by some number other than one and itself. For example, the number 6 is a composite number because it is divisible by 2 and 3 (in addition to 1 and 6) while the number 7 is prime because it is not divisible by any number other than 1 and 7.

the factors of 72 are : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.

Thus, 72 is a composite number.

prime factorization of 72: 2 x 2 x 2 x 3 x 3

Yes, because it has more than two factors

Yes. It is divisible by 7 and 47, as well as 1 and 329

Composite comes from the Latin compositus, past participle of componere 'put together.'

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

The list of non-composite numbers (being shorter) is easier to print. Composite numbers are the ones not on this list:

squares of prime numbers

A Prime number can only be divided by itself and 1 to give answers which are whole numbers. 125 can be divided by 125 and 1 but it can also be divided by 5 and 25 so it must be a composite number.

There are 14 even numbers below 3o.

They are 2, 4, 6, 8, 10, 12, 14 16, 18, 20, 22, 24, 26 and 28.

74% is the percentage of composite numbers from 1 to 100?

The composite numbers from 2 to 20 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, and 20.

53 is a prime because its only factors are 1 and itself.

No. The definition of a composite number is a natural number that isn't prime (or 1). The definition of a prime number is one with only 2 factors (itself and 1).

A composite number is the opposite of a prime number; i.e. it is any number divisible by more factors than one and itself.

15, 49, 55, 87, 91,105 are the composite numbers.

32, 33, 34, 35, 36, 38, 39, 40

No not always because composite numbers can be the product of 2 or more prime factors

12, 14, 15, 16, and 18 are composite numbers

11, 13, 17, and 19 are prime numbers

182, 183, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, 198
