No, it is not.
The least common multiple of 19 , 6 , 12 = 228
Any multiple of 38 is also a multiple of 19.
114. 19*6=114
LCM(6, 19) = 114.
The Least Common Multiple (LCM) for 20 19 6 is 1,140.

6 goes into 19 three times, as 6 multiplied by 3 equals 18, which is the largest multiple of 6 that is less than 19. The remainder when dividing 19 by 6 is 1, since 19 - 18 = 1. Therefore, the answer is 3 times with a remainder of 1.
No. To check if a number is a multiple of 3 add its digits together and if this sum is a multiple of 3, then so is the original number. This sum can be continued until a single digit remains; if the single digit is 3, 6 or 9 then the original number is a multiple of 3, otherwise not. 19 → 1 + 9 = 10 10 → 1 + 0 = 1 which is not 3, 6 or 9, so 19 is not a multiple of 3.
In a very limited sense. 19 is a common multiple of 19 and 1.
A common multiple is 19*26 = 494.
The least common multiple of 21 , 19 = 399
