The Least Common Multiple (LCM) for 4 12 21 is 84.
No, it is not possible. Every multiple of 21 is a composite number. 21 is a composite number and its factors are 1, 3, 7 and 21(4 factors). Any multiple of 21 must have all the factors of 21. So, every multiple of 21 has at least 4 factors. And a prime number has only two factors so, any multiple of 21 can't be prime.
The LCM of 3 4 21 is 84.
LCM(4, 21) = 84
32
LCM(4, 9, 21) = 252
