Any Prime number has two factors: 1 and the number itself.
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.

What is the method to find the prime factors of a composite number?
prime numbers
Which prime numbers can be mulitiplied to form?
Prime numbers are used to find the product of the prime factors of composite numbers.
How can you determine if a number is prime or composite?
Factor it. Prime numbers have two factors, composite numbers have more than two.
What are the uses of prime and composite numbers?
All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one
What are 3 digit composite numbers which are relatively prime?
Composite numbers are numbers greater than 1 that have more than two factors. Relatively prime numbers are numbers that have no common factors other than 1. Therefore, to find 3-digit composite numbers that are relatively prime, we need to look for numbers that are composite and have no common factors. An example of such a pair of 3-digit composite numbers that are relatively prime would be 119 and 143.
