## Funktionsnavn:

STØRSTE.FÆLLES.DIVISOR

Matematisk

## Resume:

Funktionen giver den største fælles divisor af to eller flere positive heltal.

## Syntaks:

STØRSTE.FÆLLES.DIVISOR(Integer 1 [; Integer 2 [; … [; Integer 255]]])

## Returnerer:

Returnerer et heltal, som er dem største fælles divisor af to eller flere positive heltal, der er opgivet som inddata.

## Argumenter:

Heltal 1, heltal 2, … , heltal 255 er heltal, referencer til celler eller celleområder med heltal, hvis største fælles divisor skal beregnes.

• * Hvis noget argument er negativt, returnerer funktionen en fejlværdi.
• Hvis noget argument ikke er et heltal, returnerer funktionen en heltals største fælles divisor. For eksempel vil STØRSTE.FÆLLES.DIVISOR(2,5:5) returnere 1, mens STØRSTE.FÆLLES.DIVISOR(8;2,2) returnerer 2.
• A reference to a single cell containing a positive integer.
• A simple reference to a cell range containing positive integers (for example, A1:B9).
• The name of a named range, comprising cells containing positive integers.
• The name of a database range, comprising cells containing positive integers.
• An inline array of positive integers (for example, {1, 2, 3, 4}).

Note that although STØRSTE.FÆLLES.DIVISOR can accept up to 255 arguments, each argument could specify a range of cells. This means that the number of positive integers processed could be many more than 255.

The following conditions (including errors) may be encountered:

• If any argument is a string in quotation marks, or a reference to a single cell that contains a string rather than a positive integer, then STØRSTE.FÆLLES.DIVISOR reports a #VÆRDI! error.
• Text and empty cells within a data range are ignored.
• If any value is negative, then STØRSTE.FÆLLES.DIVISOR reports an invalid argument error (Fejl:502).
• If any value is not an integer, that value is truncated to its floor value.
• If after any truncation all supplied values are equal to 0, then STØRSTE.FÆLLES.DIVISOR returns the value 0.

• Hvis der er givet to positIve heltal, er a*b=MINDSTE.FÆLLES.MULTIPLUM(a;b)*STØRSTE.FÆLLES.DIVISOR(a;b)
• For two positive integers i and j, the following relationship holds:
$\displaystyle{ i\times j~=~\text {\lt span lang="en" dir="ltr" class="mw-content-ltr"\gt LCM\lt /span\gt }(i, j) \times \text{\lt span lang="en" dir="ltr" class="mw-content-ltr"\gt GCD\lt /span\gt }(i, j) }$
MINDSTE.FÆLLES.MULTIPLUM(i, j) is the least common multiple of i and j (see MINDSTE.FÆLLES.MULTIPLUM).
• The greatest common divisor (STØRSTE.FÆLLES.DIVISOR) is sometimes referred to as the greatest common factor (GCF) or the highest common factor (HCF).

## Eksempler:

Formel Beskrivelse Returns
=STØRSTE.FÆLLES.DIVISOR(16; 32; 24; 40) Here the function returns 8, because that is the largest positive integer that can divide 16, 24, 32, and 40 without a remainder. 8
=STØRSTE.FÆLLES.DIVISOR(B1:B3), where cells B1, B2, and B3 contain the numbers 9, 12, and 6 respectively. Here the function returns 3, because that is the largest positive integer that can divide 6, 9, and 12 without a remainder. The formula =STØRSTE.FÆLLES.DIVISOR(B1; B2; B3) would give the same result. 3
=STØRSTE.FÆLLES.DIVISOR(3,2; 5,6) The two argument values are truncated to 3 and 5 respectively. Here the function returns 1, because that is the largest positive integer that can divide 3 and 5 without a remainder. 1
=STØRSTE.FÆLLES.DIVISOR({2; 4; 6; 8}) Here the function returns 2, because that is the largest positive integer that can divide 2, 4, 6, and 8 without a remainder. 2
