Answer: GCF of 24 and 90 is 6.

What is the GCF of 29 and 87?

Detailed Answer: The Greatest Common Factor (GCF) for 29 and 87, notation CGF(29,87), is 29.

What is the GCF for 12 and 90?

The GCF of 12 and 90 is 6.

Which is the greatest common factor of 20 and 10?

Now let’s find the GCF of our third value, 20, and our result, 10. GCF (20,10) So, the greatest common factor of 20 and 10 is 10. Therefore, the greatest common factor of 120, 50 and 20 is 10. So, the the greatest common factor of 182664 and 154875 is 177. So, the greatest common factor of 177 and 137688 is 3.

When to use GCF as the new large number?

Use b as the new large number, and subtract the final result c, repeating the same process as in Step 2 until the remainder is 0. Once the remainder is 0, the GCF is the remainder from the step preceding the zero result. From the example above, it can be seen that GCF (268442, 178296) = 2.

Which is the best method to calculate the GCF?

Larger values would make the prime factorization of each and the determination of the common factors, far more tedious. Another method used to determine the GCF involves using the Euclidean algorithm. This method is a far more efficient method than the use of prime factorization.

Which is the greatest common factor of 120, 50 and 20?

So, the greatest common factor of 20 and 10 is 10. Therefore, the greatest common factor of 120, 50 and 20 is 10. So, the the greatest common factor of 182664 and 154875 is 177. So, the greatest common factor of 177 and 137688 is 3. Therefore, the greatest common factor of 182664, 154875 and 137688 is 3. [1] Zwillinger, D. (Ed.).
