Is the greatest common factor of any two odd numbers?
The GCF of any two odd numbers is also odd.
Can two odd numbers have a greatest factor of 1?
of course. 1 is the GCF of any two prime numbers.
Is the GCF of any two even numbers is always even?
The GCF of any two odd numbers is always odd. The GCF of any two even numbers is always even. The GCF of an odd and an even number is always odd.
Why is the gcf of two odd number always odd?
Because odd numbers don't have any even factors so they can't have any in common.
Can two odd numbers have a greatest common factor?
Any non-zero set of integers has a GCF.
Is the greatest common factor of two odd numbers always 3?
No. The GCF of 25 and 35 is 5.
Is the greatest common factor of any 2 odd numbers odd?
Not only can they, but they must. An odd number cannot have an even factor. So none of the factors of either of the two odd numbers can be even and so the GCF is made up of only odd factors and so it must be odd.
Can two odd numbers have a greatest common factor of 1?
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.
Is the greatest common factor of any two odd numbers always odd?
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.
Is the gcf of any two odd numbers odd?
Yes, it has to be odd.
Is the greatest common factor always 2 when they are two odd numbers?
No. The GCF of 3 and 5 is 1. The GCF of 3 and 9 is 3.
Is the GCF of any two numbers always odd and why?
The GCF of any two odd numbers is always odd because odd numbers don't have any even factors. The GCF of any two even numbers is always even because even numbers are divisible by two and any common factors would have at least one two in common. The GCF of an even and an odd number is odd because odd numbers don't have any even factors.
