It is 42
The LCM is 63, the next is 126.
the next common multiple of 9and 21is126
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.
21 is a multiple of 7 because, 3*7 = 21
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.
For any natural number k, 21k is a multiple of k.So for example, if k=1, 21 is the first multiple.Now if k=2, we have 42 which is the next one.In fact for any number n, and any natural number k, kn is a multiple of n.
