You need at least two numbers to find a GCF.

No. The greatest common divisor for 15 and 20 is five. Five is a prime number.

It is not possible to give a sensible answer to this question. The greatest common divisor (GCD) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!

The Greatest Common Divisor of two numbers is the largest number that will divide into both evenly. For example, although 27 and 81 are both divisible by 3, it wouldn't be the greatest common divisor, because 27 divides into 81 evenly as well: the greatest common divisor of 27 and 81 is 27.

It is: 12

A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. Since 113 is a prime number, the only possible common factors are 1 or itself. It is not a factor of 650. Therefore, the only common factor and also the greatest common factor of 113 and 650 is 1.

The greatest common factor is a number that divides evenly into two or more numbers. It is also called the highest common factor or greatest common divisor.
