Multiples of 8: 72 80 88 96 104 112
72 and 96
It is: 90
Assuming you want a number that is a multiple of all of 4, 6, 9: It is a multiple of their lowest common multiple. lcm(4, 6, 9) = 36 So you require a multiple of 36 between 67 and 113: 67 ÷ 36 = 1 r 31 → 1st multiple of 36 > 67 is 2 x 36 = 72 113 ÷ 36= 3 r 5 → last multiple of 36 < 113 is 3 x 36 = 108 → both 78 and 108 are numbers between 67 and 113 which are multiples of all of 4, 6 & 9. If not, re-ask being more specific in your requirements.
There are 67.

There are 67.
* 72 * 90 * 108 All multiples of 18 are multiples of 9 and of 6, because 9 x 2 = 18, and 6 x 3 = 18. So you only have to find multiples of 18 that occur between 67 and 113. 3x18=54, no good! 4x18=72. YES 5x18=90. YES 6x18=108. YES 7x18=126, no good.
