7
The smallest number that both 21 and 23 can go into is 483.
Both 21 and 14 can go into their least common multiple, which is 42. Additionally, they can both go into any multiple of 42, such as 84, 126, and so on. Furthermore, they can also share common factors, such as 1 and 7, but in terms of multiples, 42 is the smallest number they both divide into evenly.
The number 7
It is 21 because 21/21 = 1 and 21/7 = 3

The smallest number that both 21 and 23 can go into is 483.
The number 7
The lowest common multiple - is 42 !
It is 21 because 21/21 = 1 and 21/7 = 3
The number is 154.
One.
1 and 7 both can.
21
It is: 182 and its multiples
42 as that number is the smallest number that both 3 and 14 will go into.
1 and 7 will go into both numbers evenly leaving no remainders
14 = 2*7 49 = 7*7 So 1, -1, 7, -7 all go into both 14 and 49.
