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.
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.
The greatest common factor is 18.
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 is 2.
