Given numbers are 861,493,451,779

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

The LCM of 861,493,451,779 is 88714857.

Find LCM of 861,493,451,779 with Prime Factorization

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

41 x 21 x 493 x 11 x 19 = 88714857

Therefore, the lowest common multiple of 861,493,451,779 is 88714857.

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 493 x 451 x 779 = 149129674617

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

493 : 1, 17, 29, 493

451 : 1, 11, 41, 451

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,493,451,779, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

493:17x 29

451:11x 41

779:19x 41

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

41x 41 = 1681

Therefore, the value for common factors is 1681.

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 = 149129674617/(1x1681)

LCM = 149129674617/1681

LCM = 88714857

Thus, we can understand that the LCM of 861,493,451,779 is 88714857.
