Step 2: If any of the offered numbers (4, 8, 16) is a many of 2, divide it by 2 and write the quotient below it. Lug down any kind of number that is not divisible by the element number.Step 3: proceed the actions until only 1s room left in the critical row.

The LCM that 4, 8, and also 16 is the product of all prime numbers on the left, i.e. LCM(4, 8, 16) by department method = 2 × 2 × 2 × 2 = 16.

### LCM the 4, 8, and 16 by Listing Multiples

To calculate the LCM of 4, 8, 16 by listing out the typical multiples, we have the right to follow the given below steps:

Step 1: perform a couple of multiples that 4 (4, 8, 12, 16, 20 . . .), 8 (8, 16, 24, 32, 40 . . .), and also 16 (16, 32, 48, 64, 80 . . .).Step 2: The typical multiples native the multiples that 4, 8, and 16 room 16, 32, . . .Step 3: The smallest common multiple that 4, 8, and 16 is 16.

∴ The least common multiple the 4, 8, and also 16 = 16.

### LCM of 4, 8, and also 16 by element Factorization

Prime administer of 4, 8, and 16 is (2 × 2) = 22, (2 × 2 × 2) = 23, and (2 × 2 × 2 × 2) = 24 respectively. LCM of 4, 8, and 16 can be obtained by multiply prime components raised to your respective highest power, i.e. 24 = 16.Hence, the LCM that 4, 8, and also 16 by element factorization is 16.

☛ likewise Check:

Example 1: Verify the relationship between the GCD and also LCM the 4, 8, and 16.

Solution:

The relation in between GCD and LCM that 4, 8, and 16 is provided as,LCM(4, 8, 16) = <(4 × 8 × 16) × GCD(4, 8, 16)>/⇒ prime factorization the 4, 8 and 16:

4 = 228 = 2316 = 24

∴ GCD the (4, 8), (8, 16), (4, 16) and also (4, 8, 16) = 4, 8, 4 and also 4 respectively.Now, LHS = LCM(4, 8, 16) = 16.And, RHS = <(4 × 8 × 16) × GCD(4, 8, 16)>/ = <(512) × 4>/<4 × 8 × 4> = 16LHS = RHS = 16.Hence verified.

Example 2: find the the smallest number that is divisible through 4, 8, 16 exactly.

Solution:

The the smallest number that is divisible by 4, 8, and 16 exactly is their LCM.⇒ Multiples of 4, 8, and also 16:

Multiples the 4 = 4, 8, 12, 16, 20, 24, 28, . . . .Multiples the 8 = 8, 16, 24, 32, 40, 48, 56, . . . .Multiples that 16 = 16, 32, 48, 64, 80, 96, 112, . . . .

Therefore, the LCM of 4, 8, and also 16 is 16.

Example 3: calculate the LCM of 4, 8, and 16 making use of the GCD of the given numbers.

Solution:

Prime administer of 4, 8, 16:

4 = 228 = 2316 = 24

Therefore, GCD(4, 8) = 4, GCD(8, 16) = 8, GCD(4, 16) = 4, GCD(4, 8, 16) = 4We know,LCM(4, 8, 16) = <(4 × 8 × 16) × GCD(4, 8, 16)>/LCM(4, 8, 16) = (512 × 4)/(4 × 8 × 4) = 16⇒LCM(4, 8, 16) = 16
