WORKING OUT Greatest Common Factor Uses One of the main uses of the greatest common factor is to help simplify fractions quickly. If you type in the numerator and denominator of a fraction, the calculator will tell you the GCF. You can then quickly simplify the fraction by dividing both the...
To find the GCF of two numbers, draw a factor tree for both of the numbers. Look for the common numbers among the resulting prime factors of both the trees. The GCF will be the common numbers multiplied together. For example: if 2 and 3 are common factors of two numbers, the GCF wil...
Now that we had reached 1, we ran out of prime factors. This means that we can end now the process. We may now translate it into an equation by collecting the prime factors in the first column of the table. 15 = 3 × 5 Let us do the same process for 18. Then, equate 18 to ...

Let us look at these steps in finding out the factors of a number using the factor tree method: A factor tree can be created by factorizing a number until the prime factors are found. These factors are separated and written in the form of tree branches. Let us look at how to draw the...
