function HasCommonFactor(const Factor: Int64): Boolean;
This method checks if a given value is a common factor for the fraction. The value being queried is passed in the Factor parameter.
A common factor is an integer that exactly divides both the numerator and denominator of a fraction.
The method always returns False if Factor is zero.
HasCommonFactor is useful for checking that a value is a valid common factor before passing to Simplify method.
var F: TFraction; S: string; CF: Int64; begin F := TFraction.Create(32, 48); // get common factor from user S := _; if not InputQuery('HasCommonFactor', 'Enter a factor', S) then Exit; CF := StrToInt64Def(S, 0); if F.HasCommonFactor(CF) then ShowMessageFmt( '%d is a common factor of %d/%d', [CF, F.Numerator, F.Denominator] ); end;
