25 | h4. Arabic (Saudi Arabia) | ||
26 | In Saudi Arabia and some other provinces we find the high-school math book represents the least common multiple in Arabic context. the example shows _LCM_ for 8 and 9, _م.م.أ_ means _LCM_. [Go to the example at the end of page 79 in the high school math book from ministry of education in Saudi Arabia|http://wiki.math-bridge.org/download/attachments/2883871/mathHighSchool1_part+1.pdf] or find [the math book for grade VII in our bibliography|Census.Bibliography#arMath-gradeVII] | ||

33 | We find in [the discrete math|Census.Bibliography#discrete-math-GriesAndShneider] book the example represents the least common multiple in English context. | ||
34 | [Go direcly to page 317|http://books.google.com/books?id=ZWTDQ6H6gsUC&lpg=PA201&dq=superset%20math&pg=PA317#v=onepage&q=&f=false]. | ||

41 | The example on the right denotes the least common multiple in the German book [Lineare Algebra|Census.Bibliography#lineareAlgebra-KowalskyMichler], and it is called 'Kleinstes gemeinsames Vielfaches' in german context. | ||
42 | [Go to the example in page 307|http://books.google.com/books?id=Lqn-1XzurJ4C&lpg=PA307&dq=Gr%C3%B6%C3%9Fter%20gemeinsamer%20Teiler&pg=PA307#v=onepage&q=&f=false]. | ||

50 | The Spanish [website for mathematics|http://matematicasies.com/?Calcular-el-minimo-comun-multiplo,717] shows the least common multiple in Spanish context. | ||
51 | We also find [wikipedia|http://es.wikipedia.org/wiki/M%C3%ADnimo_com%C3%BAn_m%C3%BAltiplo] shows another example in Spanish. | ||

58 | The example in page 173 represents the least common multiple in French context.

64 | h4. Finnish | ||
65 | We find that on the Helsinki University of Technology, [Department of Mathematics website|https://matta.hut.fi/matta2/isom/html/alkutekj3.html] they use _pyj_ instead of lcm, and it is called 'Pienin yhteinen jaettava' in Finnish context. | ||
66 | Also find the same ' _pyj_ ' example in [wikipedia|http://fi.wikipedia.org/wiki/Pienin_yhteinen_jaettava]. Another notation for lcm is _pym_ (pienin yhteinen monikerta). For example, this notation is used in University of Tampere, [Lecture notes by Pentti Haukkanen|http://mtl.uta.fi/Opetus/Algebra/algI04.pdf]. Usually at university level notation \[_a,b_\] is used for least common multiple of numbers _a_ and _b_ instead of letter combinations _pym_ or _pyj_. This notation is also used in lecture notes mentioned before. | ||
