All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.

All numbers have factors. Some factors are prime numbers. These are known as prime factors. Some numbers have some of the same prime factors as other numbers. These are known as common prime factors. 3 is a common prime factor of 12 and 15.
Prime factors refer to whole numbers, not decimals.
A composite factor is a factor that is a composite number, as opposed to a prime factor which is a factor that is a prime number.
Two numbers are co-prime if they do not have any common factors. The numbers themselves need not be prime.
Any factor that isn't prime.
All numbers have factors. Some factors are prime numbers. A prime factor is a factor that is a prime number. A common prime factor is a prime factor that appears on the list of factors of two or more given numbers.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
it means to find out if the number is composite or prime

All numbers have factors. Some factors are prime numbers. These are known as prime factors. A prime number only has two factors, one and itself.
All prime numbers can be factors.
That's pretty self-explanatory. Prime numbers can be factors of other numbers. 2 and 3 are prime factors of 6.
All numbers have factors. Some factors are prime numbers, some are composite numbers. A factor that is a composite number is a composite factor.
Prime number refers to what they are; prime factor refers to what they do. A number doesn't become a factor until it is multiplied. 2 and 3 are prime numbers. 2 and 3 are prime factors of 6.
