Given numbers are 810,172,389

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

The LCM of 810,172,389 is 27097740.

Find LCM of 810,172,389 with Prime Factorization

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

2 x 405 x 86 x 389 = 27097740

Therefore, the lowest common multiple of 810,172,389 is 27097740.

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.

810 x 172 x 389 = 54195480

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

172 : 1, 2, 4, 43, 86, 172

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,172,389, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

172:2x 2x 43

389:389

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

2 = 2

Therefore, the value for common factors is 2.

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 = 54195480/(1x2)

LCM = 54195480/2

LCM = 27097740

Thus, we can understand that the LCM of 810,172,389 is 27097740.
