There are 30 multiples of 30 that fall between 100 and 1,000.
297
Smallest multiple of 7 greater than 100 is 15 Largest multiple of 7 less than 1000 is 142 So number of multiples of 7 = 142 - 15 + 1 = 128
The last "x7" under 100 is 14 x 7, the last under 1000 is 142 x 7, so there are 128 in the range.
