Given numbers are 861,920,139,952,207

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

The LCM of 861,920,139,952,207 is 5615338680.

Find LCM of 861,920,139,952,207 with Prime Factorization

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

2 x 2 x 2 x 3 x 7 x 23 x 41 x 5 x 139 x 17 x 3 = 5615338680

Therefore, the lowest common multiple of 861,920,139,952,207 is 5615338680.

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 920 x 139 x 952 x 207 = 21697668659520

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

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

139 : 1, 139

952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,920,139,952,207, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

920:2x 2x 2x 5x 23

139:139

952:2x 2x 2x 7x 17

207:3x 3x 23

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

2x 2x 2x 3x 7x 23 = 3864

Therefore, the value for common factors is 3864.

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 = 21697668659520/(1x3864)

LCM = 21697668659520/3864

LCM = 5615338680

Thus, we can understand that the LCM of 861,920,139,952,207 is 5615338680.
