The least common factor of any set of positive integers is 1.
The greatest common factor is 2 and the least common multiple is also 2.
The greatest common factor is 18.
If you can find any common factor of the numerator and denominator, divide each of them by it. If you're given 18/20, you stare at it for a while, and you notice that 18 and 20 have the common factor of 2. So you divide top and bottom by 2, and you get 9/10. That's the simplest form.
It is 1 because 19 is a prime number
The Greatest Common Factor of 18, 13, and 20 is 1.
The GCF is 2.
The Greatest Common Factor (GCF) is: 2
The only common factor of 15, 18, 20, and 50 is 1.
The GCF is 2.
GCF(20, 18, 8) = 2.
The greatest common factor is 2.
Since 17 is a prime number, the greatest common factor of 17, 18, and 20 is 1.
The GCF ( greatest common factor) is 2 I know for a fact this is the correct answer Greatest common factor means the factor that goes (for example) 18 and 20, but the biggest.
The GCF is 2.
The GCF is 2.
