The positive integers up to 4 are: 1, 2, 3, and 4. This is a total of four positive integers.
There are 3,333 multiples of three that fall between 1 and 10,000.

There are 67 multiples of 6 and 50 multiples of 8 in that range. Their total, 117, will include numbers that are both.
LCM of 3 and 7 under 40 is 21
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.
