105

Step-by-step explanation:

15 X 7 =105

105 is the least 3 digit multiple of 7.

12 X 7 = 84

84 + 7 = 91

91 + 7 = 98

98 + 7 = 105

or use multiplication 13 X 7= 91, 14 X 7=98

15 X 7 = 105

This is guess and check until the sum or product is a 3 digit number. It helps if you know the 7 times table at least through 7 X 12 = 84.
