It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
Factor them.
3 x 7 = 21
2 x 2 x 3 x 5 = 60
Combine the factors, eliminating duplicates.
2 x 2 x 3 x 5 x 7 = 420, the LCM
You need at least two numbers to find an LCM.
By multiplying the the highest prime numbers which are 3 squared and 7 = 63
By comparing its multiples to the multiples of another number.
The LCM is 60.
20 and 30 have an LCM of 60.
LCM of 12 and 60 is 60.
42
The LCM is 126.
The LCM is 441.
The LCM of 9, 21 and 24 is 504.
LCM OF 9,3 AND 21 IS 63. CHECK FOR YOURSELF IF YOU ARE NOT SURE.
Of each of them on their own respectively is 28, 21 and 9. together is 252
Until that other number shows up, the LCM is 63.
7 x 9 = 63 3 x 21 = 63 Therefore, the LCM of 9 and 21 is 63.
The Least Common Multiple (LCM) for 21 3 9 is 63.
The Least Common Multiple (LCM) for 9 21 15 is 315.
The LCM is 252.
The LCM is: 63
The LCM is: 1,008
