Given numbers are 861,854,445,914

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

The LCM of 861,854,445,914 is 21361866330.

Find LCM of 861,854,445,914 with Prime Factorization

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

2 x 7 x 123 x 61 x 445 x 457 = 21361866330

Therefore, the lowest common multiple of 861,854,445,914 is 21361866330.

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.

861 x 854 x 445 x 914 = 299066128620

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

854 : 1, 2, 7, 14, 61, 122, 427, 854

445 : 1, 5, 89, 445

914 : 1, 2, 457, 914

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,854,445,914, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

854:2x 7x 61

445:5x 89

914:2x 457

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 299066128620/(1x14)

LCM = 299066128620/14

LCM = 21361866330

Thus, we can understand that the LCM of 861,854,445,914 is 21361866330.
