Answer:

91

Explanation:

You know that the number must end in 6 or 1 to get a left over of 1 when divided by 5. Six won't work because  2  divides evenly into a number ending into 6.

So the number ends in 1.

21 doesn't work because 3 divides into 21 evenly.

31 doesn't work because 7 does not divide into it.

41 doesn't work. 41 is prime. 7 won't divide into it.

51 is divisible by 3

61 seven does not evenly divide into 61.

71 seven leaves a remainder of  1

81 7 leaves a remainder.
