700edo is [[consistent]] to the [[7-odd-limit]] and its [[harmonic]] [[3/1|3]] is about halfway its steps. It is strong in the 2.9.15.7.31 [[subgroup]], [[tempering out]] [[3969/3968]], [[420175/419904]], 10255177611/10240000000 and 2202927104/2197265625. The equal temperament can also be used in the 2.9.5.7.13.17.23 subgroup, tempering out [[1225/1224]], 46000/45927, 8281/8280, 426496/426465, 31250/31213 and 262395/262144. | |||

Since 700 factors into 2<sup>2</sup> × 5<sup>2</sup> × 7, 700edo has subset edos {{EDOs| 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, and 350 }}. [[1400edo]], which doubles it, gives a good correction to the harmonic 3. | |||
