### LCM of 2, 3, and also 4 by Prime Factorization

Prime factorization of 2, 3, and 4 is (2) = 21, (3) = 31, and also (2 × 2) = 22 respectively. LCM of 2, 3, and 4 can be obtained by multiplying prime determinants raised to their corresponding highest power, i.e. 22 × 31 = 12.Hence, the LCM of 2, 3, and 4 by prime factorization is 12.

### LCM of 2, 3, and also 4 by Listing Multiples To calculate the LCM of 2, 3, 4 by listing out the prevalent multiples, we can follow the given listed below steps:

Step 1: List a few multiples of 2 (2, 4, 6, 8, 10 . . .), 3 (3, 6, 9, 12, 15 . . .), and also 4 (4, 8, 12, 16, 20 . . .).Step 2: The prevalent multiples from the multiples of 2, 3, and also 4 are 12, 24, . . .Step 3: The smallest common multiple of 2, 3, and also 4 is 12.

∴ The leastern prevalent multiple of 2, 3, and 4 = 12.

### LCM of 2, 3, and 4 by Division Method To calculate the LCM of 2, 3, and 4 by the department approach, we will divide the numbers(2, 3, 4) by their prime factors (preferably common). The product of these divisors gives the LCM of 2, 3, and 4.

Step 2: If any type of of the given numbers (2, 3, 4) is a multiple of 2, divide it by 2 and also create the quotient below it. Bring down any number that is not divisible by the prime number.Tip 3: Continue the measures until only 1s are left in the last row.

The LCM of 2, 3, and also 4 is the product of all prime numbers on the left, i.e. LCM(2, 3, 4) by division technique = 2 × 2 × 3 = 12.

Example 1: Verify the partnership between the GCD and also LCM of 2, 3, and 4.

Solution:

The relation in between GCD and LCM of 2, 3, and 4 is offered as,LCM(2, 3, 4) = <(2 × 3 × 4) × GCD(2, 3, 4)>/⇒ Prime factorization of 2, 3 and 4:

2 = 213 = 314 = 22

∴ GCD of (2, 3), (3, 4), (2, 4) and (2, 3, 4) = 1, 1, 2 and 1 respectively.Now, LHS = LCM(2, 3, 4) = 12.And, RHS = <(2 × 3 × 4) × GCD(2, 3, 4)>/ = <(24) × 1>/<1 × 1 × 2> = 12LHS = RHS = 12.Hence showed.

Example 2: Calculate the LCM of 2, 3, and 4 using the GCD of the provided numbers.

Solution:

Prime factorization of 2, 3, 4:

2 = 213 = 314 = 22

As such, GCD(2, 3) = 1, GCD(3, 4) = 1, GCD(2, 4) = 2, GCD(2, 3, 4) = 1We understand,LCM(2, 3, 4) = <(2 × 3 × 4) × GCD(2, 3, 4)>/LCM(2, 3, 4) = (24 × 1)/(1 × 1 × 2) = 12⇒LCM(2, 3, 4) = 12

Example 3: Find the smallest number that is divisible by 2, 3, 4 precisely.

Solution:

The smallest number that is divisible by 2, 3, and also 4 exactly is their LCM.⇒ Multiples of 2, 3, and also 4:

Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, . . . .Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, . . . .Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, . . . .

As such, the LCM of 2, 3, and 4 is 12.
