Given numbers are 729,86,215

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

The LCM of 729,86,215 is 313470.

Find LCM of 729,86,215 with Prime Factorization

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

43 x 729 x 2 x 5 = 313470

Therefore, the lowest common multiple of 729,86,215 is 313470.

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.

729 x 86 x 215 = 13479210

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.

729 : 1, 3, 9, 27, 81, 243, 729

86 : 1, 2, 43, 86

215 : 1, 5, 43, 215

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,86,215, is 1.

Now, the common factors can be found like this.

729:3x 3x 3x 3x 3x 3

86:2x 43

215:5x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 13479210/(1x43)

LCM = 13479210/43

LCM = 313470

Thus, we can understand that the LCM of 729,86,215 is 313470.
