21 is the smallest #. 147 / 21 = 7.
The least common multiple (LCM) of two numbers is the smallest positive rational number (not zero) that is a multiple of both. Multiples of 14 are: 14, 28, 42, 56, etc. Multiples of 21 are: 21, 42, 63,etc. The least common multiple of 14 and21 is the smallest one of those: 42
It is 576.
The smallest number that both 21 and 23 can go into is 483.

14. If you have the numbers in order like so: 7,9,11,14,21 you can see that 21 is the greater number. You then subtract 21 from the smallest number, 7, and you get 14.

21 is the smallest #. 147 / 21 = 7.
The least common multiple (LCM) of two numbers is the smallest positive rational number (not zero) that is a multiple of both. Multiples of 14 are: 14, 28, 42, 56, etc. Multiples of 21 are: 21, 42, 63,etc. The least common multiple of 14 and21 is the smallest one of those: 42
The LCM of 14 and 21 is 42. What this means is that 42 is the smallest whole number such that both 14 and 21 divide into it (without remainder). Both 14 and 21 divide into 84, for example, so 84 is a common multiple. But 42 is smaller than 84 so 84 is not the least.
21
It is 576.
The smallest number that both 21 and 23 can go into is 483.
The smallest whole number where the sum of the digits is 21 is 189. This number has a digit sum of 1+8+9 = 18. To find the smallest number with a digit sum of 21, we need to increase the hundreds digit by 1 and decrease the units digit by 1, resulting in 198.
