Given numbers are 855,431,187,431

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

The LCM of 855,431,187,431 is 68910435.

Find LCM of 855,431,187,431 with Prime Factorization

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

431 x 855 x 1 x 187 x 1 = 68910435

Therefore, the lowest common multiple of 855,431,187,431 is 68910435.

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.

855 x 431 x 187 x 431 = 29700397485

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

431 : 1, 431

187 : 1, 11, 17, 187

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,431,187,431, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

431:431

187:11x 17

431:431

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

431 = 431

Therefore, the value for common factors is 431.

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 = 29700397485/(1x431)

LCM = 29700397485/431

LCM = 68910435

Thus, we can understand that the LCM of 855,431,187,431 is 68910435.
