Given numbers are 387,489,321,163

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

The LCM of 387,489,321,163 is 6749667.

Find LCM of 387,489,321,163 with Prime Factorization

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

3 x 163 x 129 x 1 x 107 x 1 = 6749667

Therefore, the lowest common multiple of 387,489,321,163 is 6749667.

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.

387 x 489 x 321 x 163 = 9901761489

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.

387 : 1, 3, 9, 43, 129, 387

489 : 1, 3, 163, 489

321 : 1, 3, 107, 321

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,489,321,163, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

489:3x 163

321:3x 107

163:163

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

3x 3x 163 = 1467

Therefore, the value for common factors is 1467.

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 = 9901761489/(1x1467)

LCM = 9901761489/1467

LCM = 6749667

Thus, we can understand that the LCM of 387,489,321,163 is 6749667.
