Here is a true and false question

The greatest common factor of a group of natural numbers is the largest natural number that is a factor of all the numbers in a group?

Anybody know thanks
 
Pick two or three natural numbers. Find their GCF. Then check to see if the GCF has the described property.

I think i am kind of confused in what the question is answered for example the factors of 18 is 2x3x3 and 24 is 2x2x2x3 2x3=6

how would i put this into the exaqmple to see if this statement is true or false.

To get the GCF in your example, find the largest number of times that each of the prime factors repeats for each number.

For 18, there is one 2 and two 3s.
For 24, there are three 2s and one 3.

So, you select one 2 and one 3: 2 x 3 = 6 is the GCF.

How is 6 as a factor related to 18 and 24?

6 is a multiple for both numbers...so this equation statement would be true i believe am i correct?
