The LCM is 42
The LCM is: 84
To find the Least Common Multiple (LCM) of 7, 14, and 21, we first need to factorize each number. The prime factors of 7 are 7, of 14 are 2 x 7, and of 21 are 3 x 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, LCM(7, 14, 21) = 2 x 3 x 7 = 42.
42
2 x 7 = 14 3 x 7 = 21 2 x 3 x 7 = 42, the LCM
The least common multiple of the numbers 21, 14 and 7 is 42.
The LCM is: 84
It's 126. -- the 6th multiple of 21 -- the 9th multiple of 14 -- the 14th multiple of 9
The least common multiple of the numbers 7, 18 and 21 is 126.
Since 14 is a multiple of 7, it is automatically the LCM.
It is: 294 which is the same as its LCM
42, 84, 126, 168, 210 The least of these is 42.
