Therefore, the contents of this site are not suitable for any use involving risk to health, finances or property. Therefore, the greatest common factor of 182664, 154875 and 137688 is 3. Prime Factors Calculator. In the name greatest common divisor, the adjective "greatest" may be replaced by "highest", and the word "divisor" may be replaced by "factor", so that other names include highest common factor (hcf), greatest common measure, among others. Once we get the numbers down to the prime factorization, we look for the smallest power of each factor, as opposed to the largest power. Not bad, is it? So, the prime factorization of 104 is, 104 = 2 2 2 13 = 2 3 13. GCF is often used to find common denominators. The other method uses prime factors, which I discuss in the preceding section. 3. The Greatest Common Factor definition is the largest integer factor that is present between a set of numbers.It is also known as the Greatest Common Divisor, Greatest Common Denominator (GCD), Highest Common Factor (HCF), or Highest Common Divisor (HCD).This is important in certain applications of mathematics such as simplifying polynomials where often it's essential to pull out common factors. The bolded number is the largest common factor of both integers so it can be considered as the highest common factor of 60 and 40. For example, common factors of 10 and 20 are 1, 2, 5 and 10, but the highest of those is 10; therefore, the greatest common factor of 10 and 20 is 10. What is the Greatest Common Factor? Prime factorization method has a similar drawback, but since we can group all of the primes in, for instance, ascending order, we can introduce a way to work out a result a little faster than previously. Greatest common factor (GCF) of a set of numbers is the biggest factor that all the numbers share. Take the numbers 50 and 30. For smaller numbers you can simply look at the factors or multiples for each number and find the greatest common multiple of them. Dummies has always stood for taking on complex concepts and making them easy to understand. So, the greatest common factor of 177 and 137688 is 3. So the greatest common factor 76 and 84 is 4. It doesn't really mean that either of them is a prime number, just the list of shared factors is empty. Some of them are child's play, while others are more complex. This calculator only accepts positive integers as input to calculate their common factors. [1] Zwillinger, D. It is simply the largest of the common factors. Heres how to find the GCF:
