I think you want the factors of 150: 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
The only multiplies that go into 3 is 1x3 because 3 is a prime number.
(150,1)(75,2)(50,3)(30,5)(25,6)(15,10)
2,4,6,8,10.............
these are the multiples of 3 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60
3 and 7 multiplies to 21 and equals to 10
There are 50 multiples of three that fall between and one and 150.
3, 6, and 9
-3 and -3.
