The basic numerals, unlike those among the Indo-European languages (compare Proto-Indo-European numerals), are particularly divergent between all three core Altaic families and Uralic, and to a lesser extent even within Uralic.

According to Róna-Tas (1983), elevating this similarity to a hypothesis of common origin would still require several ancillary hypotheses: that this Finno-Ugric lexeme, and not the incompatible Samoyedic lexeme, is the original Uralic numeral; that this Mongolic lexeme, and not the incompatible Turkic and Tungusic lexemes, is the original Altaic numeral; that the Hungarian form with -r-, and not the -l- seen in cognates such as in Finnish kolme, is more original; that -m in the Hungarian form is originally a suffix, since -bVn, found also in other Mongolian numerals, is also a suffix and not an original part of the word root; that the voiced spirant ɣ- in Mongolian can correspond to the voiceless stop *k- in Finno-Ugric (known to be the source of Hungarian h-).
