of course. 1 is the GCF of any two prime numbers.
Of course not. In fact, the greatest common factor of two odd numbers is never 2.-- 2 is never a factor of any odd number.-- The greatest common factor of the odd numbers 651 and 1,085 is 217.
Yes.
An easy way to find the greatest commmon factor of two odd numbers would be to try dividing them by eachother.
No. Odd numbers don't have even factors.
The number will vary, but it will always be odd.
The GCF of any two odd numbers is also odd.
No.
No, it is not true: it depends on what your numbers are.
Yes, two odd numbers can have a greatest common factor of 1 if they have no factors in common. For example, 5 and 7 have a GCF of 1, as do 63 and 55.
Sure. Any two prime numbers that aren't the number two.
Because odd numbers don't have any even factors so they can't have any in common.
Yes.Yes.2 can never be a factor of an odd number and because of that it can't be a common factor of any number pair where at least one of numbers is odd.
