It will be an even number.
The GCF of two even numbers is even.
If x is an odd number that is a common factor of 2 even numbers, so is 2x. So the answer is yes.
Any two integers have a gcf. It is also possible for an odd and an even number to have a gcf other than one; for example, the following numbers (shown in factored form) have the gcf 7: 7 x 7 7 x 8 ex. 3 and 6, the GCF is 3 14 and 21 the GCF is 7
Yes and yes.
Yes.
It will be an even number.
A set of even numbers, yes.
Any consecutive even numbers have a GCF of 2.
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.
If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.
No. Odd numbers don't have even factors.
The GCF of two even numbers is even.
True. Even numbers are even because they are multiples of 2. That means that any two even numbers will have at least 2 as a common factor. Since that number (the GCF) will have 2 as a factor, it will be a multiple of 2: an even number.
The GCF of two even numbers is always even.
All even numbers have two as a factor. Any two even numbers have (at the least) two as a common factor. That means the GCF of any two even numbers will have two as a factor. Any number that has two as a factor is even.
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.
