All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The largest of these is known as the greatest common factor, or GCF.
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
That's the greatest common factor, or GCF.
Traditionally, factors are whole numbers, not decimals.
Factors refer to whole numbers, not decimals.
The easiest way to find that answer is to first factor 72 into prime format: 72 = 2x36 = 2x2x18 = 2x2x2x9 = 2x2x2x3x3 Now, look for prime numbers that occur in pairs, as any pair of like numbers in prime factorial can be combined to form a square, thus: 2x2x2x3x3 = 2(2x2)(3x3) = 2(4)(9) Lastly, multiply your square numbers together (the product of multiplying squares together will always yield another square) to get your answer: (4)(9) = 36, which is the largest whole-number, square factor of 72.
Numbers with square roots that are whole numbers
The least common factor of any set of numbers is 1 .
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The largest of these is known as the greatest common factor, or GCF.
The GCF is the largest whole number that is a factor for both of the numbers of interest. GCF is useful when simplifying fractions.
A whole number that is a factor of two or more numbers is a common factor.
Prime numbers can't have whole number square roots, of course, but the largest prime number under 400 is 397.

No odd whole numbers have 12 as a factor. 1 and 3 are odd numbers that are factors of 12.
1 is the least common factor of all whole numbers, so there is nothing to choose for a least common factor. The Greatest Common Factor (GCF) of a set of two or more numbers is the largest factor that will divide into every number in the set without leaving any remainder. 1 is the least, or smallest, factor common to all whole numbers.
It is not possible to express something as a sum of whole numbers with no common factor. All whole numbers have at least 1 as a common factor.
