For the purpose of reducing fractions to their lowest terms.
By finding the factors in both numbers and then finding the one that is greatest in common. For example the G.C.F for 45 and 36 is 9.
The greatest common multiple of any set of integers is infinite.
Divide both the numeration and the denominator by their greatest common factor.

Well, honey, the greatest common factor of 48, 72, and 36 is 12. It's like finding the one thing they all have in common, like a guilty pleasure or a favorite movie. So, grab that calculator and show those numbers who's boss!

You do not necessarily need the common prime factors when finding the greatest common factor, but with large numbers or numbers for which you cannot easily determine all the factors, using prime factorization to determine the greatest common factor is the easiest method. The greatest common factor can then be determined by multiplying the common prime factors together. For example, when trying to find the greatest common factor of 2144 and 5672, finding all their possible factors to compare could be difficult. So, it is easier to find their prime factors, determine the prime factors they have in common, and then multiply the common prime factors to get the greatest common factor.

Ah, finding the greatest common factor is like finding a happy little tree in a forest. For 36 and 81, we look for the largest number that can divide evenly into both. The greatest common factor for 36 and 81 is 9, like a gentle breeze on a sunny day.
What makes a greatest common factor "common" is comparing at least two terms and finding something common between them.

The greatest common factor is a function of two numbers-- it is the greatest factor that the numbers have in common. The concept does not apply to a single number. Now you can use the same number twice and ask what is the greatest common factor of 240 and 240 and the answer would be 240.
Yes, the greatest common factor is less than or equal to the smallest coefficient. For example, the greatest common factor of 38 and 8 is 2.
