**Answer:** LCM of 5, 6, and 9 is 90.

**Explanation: **

The LCM of three non-zero integers, a(5), b(6), and c(9), is the smallest positive integer m(90) the is divisible by a(5), b(6), and c(9) without any type of remainder.

Let's look in ~ the various methods because that finding the LCM the 5, 6, and also 9.

By Listing MultiplesBy element Factorization MethodBy division Method### LCM of 5, 6, and 9 by Listing Multiples

To calculate the LCM the 5, 6, 9 through listing out the usual multiples, we have the right to follow the given listed below steps:

**Step 1:**list a few multiples of 5 (5, 10, 15, 20, 25 . . .), 6 (6, 12, 18, 24, 30 . . .), and also 9 (9, 18, 27, 36, 45 . . .).

**Step 2:**The typical multiples indigenous the multiples the 5, 6, and also 9 space 90, 180, . . .

**Step 3:**The smallest typical multiple of 5, 6, and 9 is 90.

∴ The least typical multiple of 5, 6, and 9 = 90.

### LCM the 5, 6, and also 9 by element Factorization

Prime administrate of 5, 6, and 9 is (5) = 51, (2 × 3) = 21 × 31, and also (3 × 3) = 32 respectively. LCM the 5, 6, and 9 deserve to be acquired by multiplying prime components raised to your respective greatest power, i.e. 21 × 32 × 51 = 90.Hence, the LCM of 5, 6, and also 9 by element factorization is 90.

### LCM that 5, 6, and also 9 by division Method

To calculate the LCM the 5, 6, and 9 by the division method, we will certainly divide the numbers(5, 6, 9) by their prime determinants (preferably common). The product of this divisors provides the LCM of 5, 6, and 9.

**Step 2:**If any of the offered numbers (5, 6, 9) is a lot of of 2, divide it through 2 and also write the quotient below it. Bring down any number the is no divisible through the element number.

**Step 3:**proceed the procedures until just 1s room left in the last row.

The LCM the 5, 6, and 9 is the product of every prime numbers on the left, i.e. LCM(5, 6, 9) by division method = 2 × 3 × 3 × 5 = 90.

**☛ additionally Check:**

**Example 1: Verify the relationship between the GCD and LCM the 5, 6, and also 9.**

**Solution:**

The relation between GCD and LCM the 5, 6, and 9 is given as,LCM(5, 6, 9) = <(5 × 6 × 9) × GCD(5, 6, 9)>/

∴ GCD the (5, 6), (6, 9), (5, 9) and also (5, 6, 9) = 1, 3, 1 and 1 respectively.Now, LHS = LCM(5, 6, 9) = 90.And, RHS = <(5 × 6 × 9) × GCD(5, 6, 9)>/

**Example 2: uncover the the smallest number the is divisible by 5, 6, 9 exactly. **

**Solution: **

The worth of LCM(5, 6, 9) will certainly be the smallest number the is specifically divisible through 5, 6, and 9.⇒ Multiples the 5, 6, and 9:

**Multiples the 5**= 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, . . . ., 75, 80, 85, 90, . . . .

**Multiples of 6**= 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . . ., 72, 78, 84, 90, . . . .

**Multiples of 9**= 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, . . . ., 72, 81, 90, . . . .

Therefore, the LCM that 5, 6, and also 9 is 90.

**Example 3: calculation the LCM the 5, 6, and 9 using the GCD the the offered numbers.**

**Solution:**

Prime factorization of 5, 6, 9:

5 = 516 = 21 × 319 = 32Therefore, GCD(5, 6) = 1, GCD(6, 9) = 3, GCD(5, 9) = 1, GCD(5, 6, 9) = 1We know,LCM(5, 6, 9) = <(5 × 6 × 9) × GCD(5, 6, 9)>/
