The GCF is a relationship between whole numbers, not decimals.
The GCF of 18, 20, and 26 is 2. The GCF of a set of numbers can't be any larger than the smallest difference between the numbers. The smallest difference within this set of numbers is 2. Since all of the numbers in the set are even, 2 is the greatest common factor.
The GCF of the given numbers is 6
Since the number 7 is prime, and is not a factor of 18, the greatest common factor (GCF) of these three numbers is 1.
They can be 18 and 27
3 and 18
9 and 18
The GCF of 18 and 32 is 2.
A number can't have a factor greater than itself, so the GCF of a pair of numbers can't ever be greater than the smaller number. The GCF of 9 and 18 is 9.
Pick any two coprime numbers. Multiply both by 9. Their GCF will be 9.
18 falls between 17 and 19.
18 and 6.
