Even numbers
It can be. Two is a factor of all even numbers.
Yes. All even numbers have 2 as a factor.
Since two is a factor of all even numbers, it is a factor of 42.
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.
Two is a factor of all even numbers.
All even numbers have two as a factor.
You need at least two numbers to find a GCF. There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
Yes.
All numbers have a common factor of 1. Sometimes that's the only common factor.
Because all even numbers have two as a factor.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
