70

They both can multiply to reach it and it is the lowest one (no multiple of 7 can end on a 10 below that).

70

10 x 7 = 70

This is the lease common multiple. I know this because you cannot get 10 to have a number the same as 7 until you multiply 10 by seven itself. Just in case the multiple that is higher than this would be 140 (since it would be double the least common multiple).

Hope this helps and have a nice day.
