Given numbers are 861,815,949,286

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

The LCM of 861,815,949,286 is 14650405770.

Find LCM of 861,815,949,286 with Prime Factorization

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

13 x 861 x 815 x 73 x 22 = 14650405770

Therefore, the lowest common multiple of 861,815,949,286 is 14650405770.

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 815 x 949 x 286 = 190455275010

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

815 : 1, 5, 163, 815

949 : 1, 13, 73, 949

286 : 1, 2, 11, 13, 22, 26, 143, 286

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,815,949,286, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

815:5x 163

949:13x 73

286:2x 11x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 190455275010/(1x13)

LCM = 190455275010/13

LCM = 14650405770

Thus, we can understand that the LCM of 861,815,949,286 is 14650405770.
