Answer: None, it is impossible. No single number has a greatest common factor. A "common factor" is a factor that two or more numbers have in common. The "greatest common factor" is the largest factor that two or more numbers have in common.

When the only common factor between numerator and denominator is 1.

24 is not the greatest common factor of any single number. Common factors are the factors that two or more numbers have in common. The greatest common factor is the largest factor that two or more numbers have in common. There cannot be any common factors or a greatest common factor of a single number. There must be at least two number for common factors and a greatest common factor. Example: The greatest common factor of 24 and 48 is 24. The greatest common factor of 60 and 144 is 24. The greatest common factor of 240 and 264 is 24.

A single number does not have a common factor. Common factors are factors that two or more numbers have in common. The greatest common factor of a pair of numbers over 50 could be any number, depending on the pair of numbers. The greatest common factor of 51 and 100 is 1. The greatest common factor of 51, 52, 53, 54, 55, and 56 is 1. The greatest common factor of 52 and 100 is 2. The greatest common factor of 57 and 102 is 3.

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.

By definition, an irrational numbers cannot have any integer factors. So there can be no common factor where an irrational number is concerned.

Most rational numbers are not whole numbers. Any number which can be expressed in the form of a ratio p/q where p and q are integers with no common factor and q > 1 is a rational number which is not a whole number.

The number in the question is rational. It is not at clear how a rational number can be rationalised!

A rational number is said to be in the standard form if its denominator is a positive integer and the numerator and the denominator have no common factor other than 1 .If a rational number is not in the standard form , then it can be reduced to the standard form .

Any rational number of the form 60k/64k where k is an integer or a common factor of 60 and 64, will be equal.

All factors are whole numbers and all whole numbers are rational numbers (a rational number is one which can be expressed as one integer over another integer, and whole numbers can be expressed as themselves over 1), thus all factors are rational numbers and so all greatest common factors are rational numbers. The set of whole numbers is a [proper] subset of the set of rational numbers: ℤ ⊂ ℚ

The noun 'rational' is a singular, common noun; a word for a number that can be written as a fraction or a ratio (rational number); a word for a thing.The word 'rational' is also an adjective.

No, that's just a factor. A common factor is when that factor is also a factor of another number.
