470 = 5 × 94, and 470edo shares the [[perfect fifth|fifth]] with [[94edo]]. Unlike 94edo, however, 470edo is only [[consistent]] to the [[5-odd-limit]]. Using the [[patent val]], the equal temperament [[tempering out|tempers out]] [[703125/702464]], 823543/820125, and 1500625/1492992 in the 7-limit; [[3025/3024]], [[4000/3993]], [[6250/6237]], [[19712/19683]], and 117649/117128 in the 11-limit. It [[support]]s [[uniwiz]] and [[decimetra]].

Since 470 factors into 2 × 5 × 47, 470edo has subset edos {{EDOs| 2, 5, 10, 47, 94, and 235 }}.
Since 470 factors into {{factorisation|470}}, 470edo has subset edos {{EDOs| 2, 5, 10, 47, 94, and 235 }}.
