Given numbers are 646,533,386,936,920

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

The LCM of 646,533,386,936,920 is 275116968360.

Find LCM of 646,533,386,936,920 with Prime Factorization

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

2 x 2 x 2 x 13 x 323 x 41 x 193 x 9 x 115 = 275116968360

Therefore, the lowest common multiple of 646,533,386,936,920 is 275116968360.

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.

646 x 533 x 386 x 936 x 920 = 114448658837760

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

533 : 1, 13, 41, 533

386 : 1, 2, 193, 386

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

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 646,533,386,936,920, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

533:13x 41

386:2x 193

936:2x 2x 2x 3x 3x 13

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 13 = 416

Therefore, the value for common factors is 416.

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 = 114448658837760/(1x416)

LCM = 114448658837760/416

LCM = 275116968360

Thus, we can understand that the LCM of 646,533,386,936,920 is 275116968360.
