Given numbers are 861,785,508,993,993

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

The LCM of 861,785,508,993,993 is 113648710980.

Find LCM of 861,785,508,993,993 with Prime Factorization

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

3 x 331 x 287 x 785 x 508 x 1 x 1 = 113648710980

Therefore, the lowest common multiple of 861,785,508,993,993 is 113648710980.

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 785 x 508 x 993 x 993 = 338559510009420

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

785 : 1, 5, 157, 785

508 : 1, 2, 4, 127, 254, 508

993 : 1, 3, 331, 993

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,785,508,993,993, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

785:5x 157

508:2x 2x 127

993:3x 331

993:3x 331

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

3x 3x 331 = 2979

Therefore, the value for common factors is 2979.

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 = 338559510009420/(1x2979)

LCM = 338559510009420/2979

LCM = 113648710980

Thus, we can understand that the LCM of 861,785,508,993,993 is 113648710980.
