Well, isn't that a happy little math problem! To find the Least Common Multiple (LCM) of 21, 42, and 84, we look for the smallest number that all three can divide into evenly. First, we see that 84 is the largest number, so we start by checking if it is divisible by 21 and 42. Since 84 is divisible by both 21 and 42, the LCM of 21, 42, and 84 is 84. Just like painting a beautiful landscape, it's all about finding harmony and balance in numbers!
To find the Least Common Multiple (LCM) of 21, 42, and 84, we need to first factorize each number into its prime factors.
21 = 3 x 7 42 = 2 x 3 x 7 84 = 2 x 2 x 3 x 7
Then, we take the highest power of each prime factor that appears in any of the numbers: 2^2 x 3 x 7 = 84.
Therefore, the LCM of 21, 42, and 84 is 84.
The LCM is 84.
The least common multiple (LCM) of 21 and 42 is 42.
The least common multiple of 14 and 21 is 42.14, 28, 42, 56 ...21, 42, 63, 84, ...
252 is the LCM of 21, 84, and 126.
LCM of 14 28 42 is 84.
LCM(21, 28, 42) = 84
For the values: 21, 14 the LCM is: 42
LCM(21, 28, 42) = 84.
The LCM of 14 and 21 is 42. What this means is that 42 is the smallest whole number such that both 14 and 21 divide into it (without remainder). Both 14 and 21 divide into 84, for example, so 84 is a common multiple. But 42 is smaller than 84 so 84 is not the least.
The LCM is: 84
The LCM is 84.
hcf = 42, lcm = 84.
The LCM of 12 and 42 is 84.
The LCM would be 84, since 42 divides into 84 exactly twice !
84
The LCM of 24, 42, and 84 is 168.
LCM(4, 21, 14) = 84
