Given numbers are 18,27,765

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 18,27,765 is 4590.

Find LCM of 18,27,765 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 3 x 2 x 3 x 85 = 4590

Therefore, the lowest common multiple of 18,27,765 is 4590.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

18 x 27 x 765 = 371790

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

18 : 1, 2, 3, 6, 9, 18

27 : 1, 3, 9, 27

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,27,765, is 9.

Now, the common factors can be found like this.

18:2x 3x 3

27:3x 3x 3

765:3x 3x 5x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 371790/(9x9)

LCM = 371790/81

LCM = 4590

Thus, we can understand that the LCM of 18,27,765 is 4590.
