Given numbers are 215,873,431,390

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

The LCM of 215,873,431,390 is 2103310170.

Find LCM of 215,873,431,390 with Prime Factorization

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

3 x 5 x 43 x 291 x 431 x 26 = 2103310170

Therefore, the lowest common multiple of 215,873,431,390 is 2103310170.

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.

215 x 873 x 431 x 390 = 31549652550

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.

215 : 1, 5, 43, 215

873 : 1, 3, 9, 97, 291, 873

431 : 1, 431

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,873,431,390, is 1.

Now, the common factors can be found like this.

215:5x 43

873:3x 3x 97

431:431

390:2x 3x 5x 13

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 31549652550/(1x15)

LCM = 31549652550/15

LCM = 2103310170

Thus, we can understand that the LCM of 215,873,431,390 is 2103310170.
