Given numbers are 173,431,787,580,920

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

The LCM of 173,431,787,580,920 is 1565611241080.

Find LCM of 173,431,787,580,920 with Prime Factorization

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

2 x 2 x 5 x 173 x 431 x 787 x 29 x 46 = 1565611241080

Therefore, the lowest common multiple of 173,431,787,580,920 is 1565611241080.

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.

173 x 431 x 787 x 580 x 920 = 31312224821600

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.

173 : 1, 173

431 : 1, 431

787 : 1, 787

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

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 173,431,787,580,920, is 1.

Now, the common factors can be found like this.

173:173

431:431

787:787

580:2x 2x 5x 29

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 5 = 20

Therefore, the value for common factors is 20.

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 = 31312224821600/(1x20)

LCM = 31312224821600/20

LCM = 1565611241080

Thus, we can understand that the LCM of 173,431,787,580,920 is 1565611241080.
