Given numbers are 641,418,859,859

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

The LCM of 641,418,859,859 is 230158742.

Find LCM of 641,418,859,859 with Prime Factorization

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

859 x 641 x 418 x 1 x 1 = 230158742

Therefore, the lowest common multiple of 641,418,859,859 is 230158742.

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.

641 x 418 x 859 x 859 = 197706359378

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.

641 : 1, 641

418 : 1, 2, 11, 19, 22, 38, 209, 418

859 : 1, 859

859 : 1, 859

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,418,859,859, is 1.

Now, the common factors can be found like this.

641:641

418:2x 11x 19

859:859

859:859

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

859 = 859

Therefore, the value for common factors is 859.

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 = 197706359378/(1x859)

LCM = 197706359378/859

LCM = 230158742

Thus, we can understand that the LCM of 641,418,859,859 is 230158742.
