6 is a correct✅
The number you seek is 78 - it is a multiple of both 6 and 26 and is less than 85. To be a multiple of both 6 and 26 it must be a multiple of their lowest common multiple: 6 = 2 x 3 26 = 2 x 13 lcm = 2 x 3 x 13 = 78 So it must be one of 78, 156, 234, ...; only 78 satisfies the criteria of being less than 85.
989. If there is a remainder of 2 when divided by 3, the number is one less than a multiple of 3. If there is a remainder of 4 when divided by 5, the number is one less than a multiple of 5. Thus the number required is one less than a multiple of the lowest common multiple of 3 and 5 (that is 15). So what is needed is an even multiple of 15 less than or equal to 1000: 1000 ÷ 15 = 662/3 Thus the highest even multiple of 15 not greater than 1000 is 66 x 15 = 990, and the required number is 989.

The multiple of 4 less than 15 is 12. A multiple is the result of multiplying a number by an integer. In this case, 4 multiplied by 3 equals 12, which is less than 15. Therefore, the multiple of 4 less than 15 is 12.
It is either two quantities that are larger or smaller than the ones that you started with, depending on whether the number that you multiplied or divided by was greater than or less than 1.Multiply by a number greater than 1 : both larger.Multiply by a number less than 1 : both smaller.Divide by a number greater than 1 : both smaller.Divide by a number less than 1 : both larger.
Both 21 and 42 will work. ■

The only number that satisfies both conditions is... 15
4 and 16 both qualify.
No. A multiple cannot be less than the number it is compared to. An LCM can never be less than the greatest number in the set.

No. A common multiple is a multiple of both numbers. There is no multiple of 17 that is less than 17.
It is 30.
This number could be 120 or 240.
