It is 120, 150, and 180.
There are 5 multiples of 18 between 200 and 300. (An even number divisible by 9 is any number divisible by 18).
200
Any number that is divisible by 100 is also divisible by 20. so 100, 200, 300, 400 etc
235
150
There are 33 numbers between 200 and 300 that are divisible by three.
A number that is divisible by 4 and 6 must be divisible by the LCM of 4 and 6 which is 12. 100/12 = 8.33 200/12 = 16.67 So, there are 16 numbers below 200 that are divisible by 4 and 6 and, of these, 8 are smaller than 100. That gives 16 - 8 = 8 between 100 and 200.
It is 120, 150, and 180.
There are 22 such numbers.
12. 13, if you count 200
100 ÷ 6 = 16 r 4 so the first whole number between 100 and 200 divisible by 6 is 6 x 17 (= 102) 200 ÷ 6 = 33 r 2 so the last whole number between 100 and 200 divisible by 6 is 6 x 33 (= 198) So the whole numbers between 100 and 200 divisible by 6 are the multiples of 6 from 17 to 33 which are: 102, 108, 114, 120, 126, 132, 138, 144, 150, 156, 162, 168, 174, 180, 186, 192 and 198.
There are 5 multiples of 18 between 200 and 300. (An even number divisible by 9 is any number divisible by 18).
Because the smallest such number is 210.
200
The numbers between 100 and 200 that are divisible by three but not by two are: 105, 111, 117, 123, 129, 135, 141, 147, 153, 159, 165, 171, 177, 183, 189 and 195.
2 times 3 times 5 is 30 so you just have to have a number divisible by 30 so 120.
