LCM of 2, 4, 6, and 8 by Listing Multiples
To calculate the LCM of 2, 4, 6, 8 by listing out the common multiples, we can follow the given below steps:

Step 1:
List a few multiples of 2 (2, 4, 6, 8, 10 . . .), 4 (4, 8, 12, 16, 20 . . .), 6 (6, 12, 18, 24, 30 . . .), and 8 (8, 16, 24, 32, 40 . . .). 
Step 2:
The common multiples from the multiples of 2, 4, 6, and 8 are 24, 48, . . . 
Step 3:
The smallest common multiple of 2, 4, 6, and 8 is 24.
∴ The least common multiple of 2, 4, 6, and 8 = 24.
LCM of 2, 4, 6, and 8 by Prime Factorization
Prime factorization of 2, 4, 6, and 8 is (2) = 2^{1}, (2 × 2) = 2^{2}, (2 × 3) = 2^{1}
× 3^{1}, and (2 × 2 × 2) = 2^{3}
respectively. LCM of 2, 4, 6, and 8 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 2^{3}
× 3^{1}
= 24.
Hence, the LCM of 2, 4, 6, and 8 by prime factorization is 24.
LCM of 2, 4, 6, and 8 by Division Method
To calculate the LCM of 2, 4, 6, and 8 by the division method, we will divide the numbers(2, 4, 6, 8) by their prime factors (preferably common). The product of these divisors gives the LCM of 2, 4, 6, and 8.

Step 1:
Find the smallest prime number that is a factor of at least one of the numbers, 2, 4, 6, and 8. Write this prime number(2) on the left of the given numbers(2, 4, 6, and 8), separated as sendirisendiri the ladder arrangement. 
Step 2:
If any of the given numbers (2, 4, 6, 8) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number. 
Step 3:
Continue the steps until only 1s are left in the last row.
The LCM of 2, 4, 6, and 8 is the product of all prime numbers on the left, i.e. LCM(2, 4, 6, 8) by division method = 2 × 2 × 2 × 3 = 24.
