For example, what are some common multiples of 3 and 5? We can start by listing some multiples of 3: 3,6,9,12,15,18,21,24,27,30,33… Next, list the multiples of 5: 5,10,15,20,25,30,35,40… Now, the numbers common to both lists are: 15,30. The smallest positive integer on the list is the least common multiple.
How many numbers between 1 and 200 are divisible by either 2 or 3 or 5?
Thus, there are 33 numbers between 1 and 200 which are divisible by both 2 and 3.
How many numbers are there between 1 to 200 which are divisible by 3?
The largest number between 1 and 200 divisible by 3 is 198 and the smallest is 3. Therefore the number of numbers between 1 and 200 divisible by 3 is (198 – 3)/3 + 1 = 66.
How many numbers up to 200 are divisible by both 4 and 3 together?
Answer. Divisible by 3 and 4 together is divisible by 12. So such numbers will be upto 200 will be 16.
How many numbers are divisible by 2 or 3?
75 numbers are divisible by 2 and 3 .
How many numbers between 200 and 500 that are multiple of 3?
Hence there are exactly 100 -25 = 75 numbers between 200 and 500 which are multiples of 3, but are not multiples of 12.
How many multiples of 8 are there between 200 and 500?
200 =3×66 +2, and 500 = 3×166 +2, and hence expectedly there are 166–66 =100 multiples of 3 between 200 and 500. Similarly 200 = (12×16)+8 and 500 = (12×41)+8, and so there are 41 -16 =25 multiples of 12 between 200 and 500, each of which also happens to be multiples of 3 also.
Are there any calculators that calculate multiples of 1?
