Calculates the greatest common divisor (GCD) of two arbitrary precision integers provided as decimal strings, returning the result as a string.

Examples

PRINT BIGGCD$("48", "18")

Produces "6".

PRINT BIGGCD$("12345678901234567890", "9876543210")

Produces "90".

PRINT BIGGCD$("-42", "56")

Produces "14".

Notes

Inputs must be valid base-10 integer strings.
Negative values are treated by magnitude (the result is always non-negative).
If both inputs are zero, the result is "0".
Result is returned as a decimal string.
