Given numbers are 863,820,452,940,920

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

The LCM of 863,820,452,940,920 is 172885583960.

Find LCM of 863,820,452,940,920 with Prime Factorization

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

2 x 2 x 5 x 863 x 41 x 113 x 47 x 46 = 172885583960

Therefore, the lowest common multiple of 863,820,452,940,920 is 172885583960.

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.

863 x 820 x 452 x 940 x 920 = 276616934336000

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.

863 : 1, 863

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

452 : 1, 2, 4, 113, 226, 452

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,820,452,940,920, is 1.

Now, the common factors can be found like this.

863:863

820:2x 2x 5x 41

452:2x 2x 113

940:2x 2x 5x 47

920:2x 2x 2x 5x 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 2x 2x 2x 5x 5 = 1600

Therefore, the value for common factors is 1600.

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 = 276616934336000/(1x1600)

LCM = 276616934336000/1600

LCM = 172885583960

Thus, we can understand that the LCM of 863,820,452,940,920 is 172885583960.
