**most efficient way find the greatest common factor of 3**

The GCF of three numbers can be computed as GCF(a, b, c) = GCF(GCF(a, b), c), or in some different way by applying commutativity and associativity. This can be extended to any number of numbers. This can be extended to any number of numbers.... The GCF is 3, so the new GCF is 2 * 3 * 3 = 18 The new set is 3,9,7 ; it contains 2 prime numbers that are different; i.e. the numbers cannot be factored anymore, so the algorithm stops and the answer is GCF=18 Find the GCD of the first two. Then the GCD of that and the third one. With small numbers

**Greatest Common Factor of 3 Numbers using a Factor Tree**

Example. Find the common factors for 60 and 30. Begin by factoring both numbers. Find all factors that the numbers have in common. The product of all common factors is the greatest common factor (GCF)... The greatest common factor (the greatest number in the list of common factors) To be a multiple of all three numbers, we first need the shared (common) factors. These are the numbers in parentheses on the left below, or the vertical (circled) numbers on the right. To be a multiple of all three numbers, we also need the non-shared factors. These are the numbers after the parentheses on the

**GCF of 3 and 6 Greatest Common Factor of 3 and 6**

Note: To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to … how to grow hyacinth bulbs outdoors Given three numbers, the method of finding greatest common factor is same as the method of finding gcf of two numbers. We list all the factors of the three numbers. We look for the common factors of these numbers.

## How To Find The Greatest Common Factor Of Three Numbers

To find the greatest common factor of two or more integers, the common prime factors of each number are multiplied together. The result is the greatest common factor of those two or more integers.

- The largest factor common to all numbers is the greatest common factor. To find the factors of a number, divide by 2, if the result is a whole number than both 2 and the result are factors. Repeat this process by dividing by 3, 4, and so on until you’ve reached 1.
