When they have a factor in common greater than one.
Always equal to or less than the smaller number, yes.
24 and 36
The factors of 5 are: 1, and 5The factors of 10 are: 1, 5, and 10The factors common to 5 and 10 are: 1, and 5The greatest common factor is 5.
The greatest common factor of 20b6 and 14b is 2b.
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.
It can and is.
It can be and it is.
Yes, the greatest common factor of 16 and 42 can be and is less than 16. The GCF of 16 and 42 is 2..
It isn't.
6
It can be and is.
When they have a factor in common greater than one.
Since 16 is not a factor of 40, the GCF must be less than 16.
If we are trying to find the two numbers less than 50 with the greatest common factor, we need to pick two numbers with a larger difference between them, since the greatest common factor between two numbers cannot be greatest than the difference between the two numbers. To create a large difference, we will want one number to be close in value to 50. And, for the greatest common factor, we want the other number itself to be the greatest common factor. The greatest common factor that the larger number can have (since it is larger and thus cannot be the greatest common factor itself) is the number which is half its value. So, if we choose the even number closest in value to 50, we get 48. Then, if we take half of it, we get 24. The greatest common factor of 24 and 48 is 24. This is the largest possible greatest common factor of a pair of numbers less than 50.
Oh, absolutely! The greatest common factor of 16 and 42 can indeed be less than 16. In this case, the greatest common factor of 16 and 42 is 2, which is less than 16. It's all about finding the largest number that can evenly divide both 16 and 42, no matter how big or small it may be.
254 cannot have a greatest common factor. To have a greatest common factor, there must be more than one number involved
