Given numbers are 391,920,580,536,820

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

The LCM of 391,920,580,536,820 is 1245929320.

Find LCM of 391,920,580,536,820 with Prime Factorization

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

2 x 2 x 2 x 5 x 23 x 17 x 1 x 29 x 67 x 41 = 1245929320

Therefore, the lowest common multiple of 391,920,580,536,820 is 1245929320.

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.

391 x 920 x 580 x 536 x 820 = 91700397952000

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.

391 : 1, 17, 23, 391

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

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

536 : 1, 2, 4, 8, 67, 134, 268, 536

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,920,580,536,820, is 1.

Now, the common factors can be found like this.

391:17x 23

920:2x 2x 2x 5x 23

580:2x 2x 5x 29

536:2x 2x 2x 67

820:2x 2x 5x 41

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 2x 5x 5x 23 = 73600

Therefore, the value for common factors is 73600.

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 = 91700397952000/(1x73600)

LCM = 91700397952000/73600

LCM = 1245929320

Thus, we can understand that the LCM of 391,920,580,536,820 is 1245929320.
