Easiest way to find the gcf
WebDec 1, 2024 · Example: Both 15 and 21 share two common factors: 1 and 3. The GCF for the two terms of the original ratio is 3. 5. Divide both terms by the greatest common factor. Since both terms of the original ratio contain the GCF, you can divide each term by that number and come up with whole numbers as a result.

WebNov 12, 2015 · The easiest way to find the GCF of 2 numbers is the Euclidean method. It is somewhat awkward to explain but once understood, is very easy to use. The idea here is to make the numbers that you are dealing with smaller and smaller so as to simplify the problem. Suppose you start with the two numbers p and q where p > q.
Web35 – 25 = 10, so 10 is the greatest possible GCF. But of course 10 does not go into 25 and 35, so 10 is not the GCF. Check the numbers less than 10, and you’ll see that 5 is the … WebAlso known as the ladder method, the upside-down division is probably the easiest way to find the GCF of two numbers. You start off by placing both values in the general ladder division symbol. Then you divide the values by prime numbers in ascending order. And you keep on dividing if and only both values are divisible.

The only way to teach this is by example, so that’s what I’ll do — by finding the LCM for 18 and 30. Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6. Step 2) Divide that GCF into either number; it doesn’t matter which one you choose, so choose the one that’s easier to divide. Choose 18.
