It is 42
The next common multiple of 9 and 21 can be found by determining their least common multiple (LCM). The LCM of 9 and 21 is 63, as it is the smallest number that both 9 and 21 divide evenly into. Therefore, the next common multiple of 9 and 21, after 0, is 63.
The LCM is 63, the next is 126.

180
21, 28, 35, 42, 49
Their lowest common multiple is 63.
the next multiple of 3 is 6 more multiples of 3 would be... 9, 12 ,15 ,18, 21, 24, 27, 30, 33 etc..
There isn't one.
No but 21 is a multiple of 3 because 7*3 = 21
No, but 21 is a multiple of 7.
Multiples of 3: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30Add three to get the next multiple; the multiples go on forever.Multiples of 2: 0,2,4,6,8,10,12,14,16,18,20Add two to get the next multiple; the multiples go on forever.Multiples of 3 and 2: 6, 12, 18, 24, 30, ...Add six to get the next multiple; the multiples go on forever.
21 can go into 68 three times, as 21 multiplied by 3 equals 63, which is the largest multiple of 21 that is less than or equal to 68. The next multiple, 21 times 4, equals 84, which exceeds 68. Therefore, 21 fits into 68 a total of 3 times with a remainder of 5.
