**Answer:** LCM the 4, 5, and also 8 is 40.

**Explanation: **

The LCM of 3 non-zero integers, a(4), b(5), and c(8), is the smallest positive integer m(40) the is divisible by a(4), b(5), and also c(8) without any kind of remainder.

The methods to uncover the LCM of 4, 5, and also 8 are defined below.

By department MethodBy prime Factorization MethodBy Listing Multiples### LCM the 4, 5, and 8 by division Method

To calculate the LCM that 4, 5, and 8 by the department method, we will certainly divide the numbers(4, 5, 8) by their prime components (preferably common). The product of this divisors offers the LCM of 4, 5, and also 8.

**Step 2:**If any of the given numbers (4, 5, 8) is a many of 2, division it by 2 and write the quotient below it. Bring down any type of number that is no divisible through the element number.

**Step 3:**continue the measures until only 1s room left in the critical row.

The LCM of 4, 5, and 8 is the product of all prime number on the left, i.e. LCM(4, 5, 8) by department method = 2 × 2 × 2 × 5 = 40.

### LCM the 4, 5, and 8 by prime Factorization

Prime administer of 4, 5, and also 8 is (2 × 2) = 22, (5) = 51, and (2 × 2 × 2) = 23 respectively. LCM that 4, 5, and 8 deserve to be obtained by multiplying prime components raised to their respective highest power, i.e. 23 × 51 = 40.Hence, the LCM the 4, 5, and also 8 by prime factorization is 40.

### LCM of 4, 5, and also 8 by Listing Multiples

To calculate the LCM that 4, 5, 8 by listing the end the typical multiples, we have the right to follow the given listed below steps:

**Step 1:**perform a few multiples of 4 (4, 8, 12, 16, 20 . . .), 5 (5, 10, 15, 20, 25 . . .), and also 8 (8, 16, 24, 32, 40 . . .).

**Step 2:**The common multiples native the multiples of 4, 5, and also 8 space 40, 80, . . .

**Step 3:**The smallest common multiple the 4, 5, and also 8 is 40.

∴ The least typical multiple the 4, 5, and also 8 = 40.

**Example 2: Verify the relationship between the GCD and also LCM that 4, 5, and also 8.**

**Solution:**

The relation between GCD and LCM the 4, 5, and 8 is provided as,LCM(4, 5, 8) = <(4 × 5 × 8) × GCD(4, 5, 8)>/

∴ GCD of (4, 5), (5, 8), (4, 8) and (4, 5, 8) = 1, 1, 4 and also 1 respectively.Now, LHS = LCM(4, 5, 8) = 40.And, RHS = <(4 × 5 × 8) × GCD(4, 5, 8)>/

**Example 3: find the smallest number that is divisible through 4, 5, 8 exactly. **

**Solution: **

The the smallest number that is divisible by 4, 5, and 8 precisely is your LCM.⇒ Multiples that 4, 5, and also 8:

**Multiples that 4**= 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, . . . .

**Multiples the 5**= 5, 10, 15, 20, 25, 30, 35, 40, . . . .

**Multiples that 8**= 8, 16, 24, 32, 40, . . . .

Therefore, the LCM of 4, 5, and 8 is 40.
