### LCM that 8, 10, and 15 by Listing Multiples To calculate the LCM the 8, 10, 15 by listing the end the typical multiples, we deserve to follow the given below steps:

Step 1: list a few multiples that 8 (8, 16, 24, 32, 40 . . .), 10 (10, 20, 30, 40, 50 . . .), and also 15 (15, 30, 45, 60, 75 . . .).Step 2: The typical multiples indigenous the multiples of 8, 10, and 15 space 120, 240, . . .Step 3: The smallest common multiple of 8, 10, and also 15 is 120.

∴ The least usual multiple the 8, 10, and also 15 = 120.

### LCM of 8, 10, and 15 by division Method To calculate the LCM that 8, 10, and 15 through the division method, we will divide the numbers(8, 10, 15) by their prime components (preferably common). The product of this divisors provides the LCM the 8, 10, and also 15.

Step 2: If any of the offered numbers (8, 10, 15) is a lot of of 2, division it by 2 and write the quotient below it. Bring down any kind of number that is not divisible by the prime number.Step 3: continue the measures until only 1s room left in the critical row.

The LCM the 8, 10, and 15 is the product of every prime number on the left, i.e. LCM(8, 10, 15) by division method = 2 × 2 × 2 × 3 × 5 = 120.

### LCM of 8, 10, and 15 by prime Factorization

Prime administer of 8, 10, and also 15 is (2 × 2 × 2) = 23, (2 × 5) = 21 × 51, and (3 × 5) = 31 × 51 respectively. LCM that 8, 10, and 15 can be obtained by multiply prime factors raised to your respective greatest power, i.e. 23 × 31 × 51 = 120.Hence, the LCM that 8, 10, and also 15 by prime factorization is 120.

Example 3: Verify the relationship between the GCD and also LCM the 8, 10, and also 15.

Solution:

The relation between GCD and LCM the 8, 10, and 15 is given as,LCM(8, 10, 15) = <(8 × 10 × 15) × GCD(8, 10, 15)>/⇒ prime factorization that 8, 10 and also 15:

8 = 2310 = 21 × 5115 = 31 × 51

∴ GCD that (8, 10), (10, 15), (8, 15) and also (8, 10, 15) = 2, 5, 1 and 1 respectively.Now, LHS = LCM(8, 10, 15) = 120.And, RHS = <(8 × 10 × 15) × GCD(8, 10, 15)>/ = <(1200) × 1>/<2 × 5 × 1> = 120LHS = RHS = 120.Hence verified. ## FAQs on LCM that 8, 10, and also 15
