There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
All nonzero numbers have an infinite number of multiples.
There are seven multiples of six that fall between one and 50: 12, 18, 24, 30, 36, 42, 48.
There are four: 6, 12, 18, 24.
12, 24, 36, 48 - the multiples of 12.
That's the same as asking how many multiples of 12 are between 1 and 150 and since 12 x 12 = 144, your answer is 12.
The multiples of 2 between 7 and 15 are 8, 10, 12, and 14.
There are six multiples of both 2 and 3 that fall between 1 and 40. They are: 6, 12, 18, 24, 30, 36.
