## Greatest Common Factor and Least Common Multiple

The most efficient method you use depends on how many numbers you have, how large they are and what you will do with the result. Factoring To find the GCF by factoring, list out all of the factors of each number or find them with a Factors Calculator.

The whole number factors are numbers that divide evenly into the number with zero remainder. Given the list of common factors for each number, the GCF is the largest number common to each list. Find the GCF of 18 and 27 The factors of 18 are 1, 2, 3, 6, 9, The factors of 27 are 1, 3, 9, The common factors of 18 and 27 are 1, 3 and 9. The greatest common factor of 18 and 27 is 9. Find the GCF of 20, 50 and The factors of 20 are 1, 2, 4, 5, 10, The factors of 50 are 1, 2, 5, 10, 25, The factors of are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, The common factors of 20, 50 and are 1, 2, 5 and Include only the factors common to all three numbers.

The greatest common factor of 20, 50 and is Prime Factorization To find the GCF by prime factorization, list out all of the prime factors of each number or find them with a Prime Factors Calculator. List the prime factors that are common to each of the original numbers.

Include the highest number of occurrences of each prime factor that is common to each original number. Let's say that our two numbers are 18 and 24, and we want to find the GCF.

From a factor tree, we know that: So we have as our factors: For a number to be the GCF of 18 and 24, it must be a factor of 18, right? If it's not, then there's no way it can be a greatest common factor of 18 and something else.

### Greatest Common Factor Calculator

If our GCF is a factor if 18, then it must be made up of some combination of 2s and 3s with at most one 2 and at most two 3s. Do you see why? Now, our GCF also has to be a factor of 24, so what does that mean about the numbers that make it up? Right, it has to be some combination of 2's and 3's, with no more than three 2's and no more than one 3.

### Greatest Common Factor (GCF)

Remember the factors of Let's summarize what we've done so far. We're looking for the GCF of 18 and We know from our factor tree that: We also know certain things about the factors of the GCF itself.

**9 Reasons Why Older Men Like Dating Younger Women**

Because we factored the 18, we know it is made up of 2's and 3's, and it can have no more than one 2 and no more than two 3s. Because we factored the 24, we know that it is made up of 2s and 3s, with no more than three 2's and one 3. When we put this all together, what do we have?

Well, our GCF must have only 2's and 3's as its factors. We also know that it can have no more than one 2 as a factor from the
