Finnish
On the Helsinki University of Technology, Department of Mathematics website, we find that they use syt instead of gcd, and it is called 'Suurin yhteinen tekijä' in Finnish context.
Also find syt in wekipedia. Usually at university level notation (a,b) is used for greatest common divisor of numbers a and b instead of letter combination syt. For example see Lecture notes by Pentti Haukkanen at University of Tampere.
