12 of them.
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.
There are four multiples of 12 between 150 and 200: 156, 168, 180, 192
To find the integers between 100 and 150 that can be divided by either 3 or 4, we can first calculate the multiples of 3 and 4 in that range. The multiples of 3 between 100 and 150 are 102, 105, ..., 150, giving us 17 multiples. The multiples of 4 are 100, 104, ..., 148, which gives us 13 multiples. We also need to exclude the overlap (multiples of 12) which are 108, 120, 132, 144, totaling 4. Thus, the total count is 17 + 13 - 4 = 26 integers.
12 of them.
32 of them.
One
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
The first one in this range is 9, then you add 3 to get the next number: 9, 12, 15, 18, ...., 144, 147, 150. There are a total of 48 numbers. ((150-9)/3)+1
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.
150, 300, 450, 600, 750, 900, 1050, 1200, 1350, 1500, 1650, 1800.
There are four: 6, 12, 18, 24.
