How do you use prime factorization to find the GCF of three numbers?
You can find the prime factors of all three numbers, combine (multiply) those numbers and remove redundant factors. So if your numbers are 4, 6 and 8, then those factors are (2*2), (3*2), and (2*2*2) respectively. The GCF is 24 or (2*2*2*3). This is because 24 can be written as a multiple of all three numbers because 24 can be written as a multiple of 2 4 and 6. (2*2*3*(2)) (2*3*(4)) and (2*2*(6)). If this is still unclear you can check the Wikipedia Article on LCM.
Is 3 a prime or composite number why?
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
What are coposite numbers?
Composite numbers are those numbers which have more than 2 factors. Example: 4 has more than 2 factors (factors of 4 are- 1, 2 and 4) and hence is a composite number. Other examples are 6, 8, 9, 10, 12 etc.
What is the name of the two number you multiply together?
Factors. example: 2 x 2 = 4 there, 2 and 2 are the 2 numbers you multiply, factors are the numbers you multiply together. It can be more that 2 factors.

Three greatest common factors of 4?
Four only has three factors: 1, 2 and 4. For any of them to be a GCF, they need to be compared to another set of numbers.
What are numbers that have 2 4 8 factors?
Numbers that have 2 factors are prime numbers; Numbers that have 4 factors are either: * the cube of a prime; or * the product of two different primes; Numbers that have 8 factors are either: * a prime to the power 7; * the product of a prime cubed and different prime; * the product of three different primes.
