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.
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.
What times what times what equals 36?
To find three numbers that multiply to 36, we need to consider the factors of 36. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. To find three numbers that multiply to 36, we can choose any combination of these factors. For example, one possible set of numbers could be 2 x 2 x 9 = 36.
What are the four factors of 4?
Four has only three factors: 1 2 4.
