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
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.
LCM(4, 9, 21) = 252
The least common multiple of the numbers 4, 614 and 21 is 25,788.
