You need at least two numbers to find a GCF.The greatest factor of 18 is itself
You choose any number for the first factor. Then you divide 18 by that first factor to get the second factor.
You need at least two numbers to find a GCF.
The greatest common factor (GCF) is 3.
8 4,2 2,2,2 18 9,2 3,3,2 The GCF is 2.
The GCF is 6.

Factor 18 and y then look for the largest common factor form both sets of factors. For example, the factors of 18 are 2,3,6,9,18 if y = 30, then its factors are 2,3,5,6,10,15,30 So the greatest common factor is 6
Of course, it doesn't have to be chairs. Some people find that visualizing objects is helpful in manipulating abstract things like numbers. If you can arrange the chairs in rectangles with no stray chairs left over, you will find that the dimensions of the rectangles correspond to the factors. 1 x 18 2 x 9 3 x 6
No, 18 is a multiple of 6. 6 is a factor of 18.
72 is not a factor of 18; 18 is a factor of 72.
18 is the greatest factor of 18.
