Given numbers are 921,867,780,675,581

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

The LCM of 921,867,780,675,581 is 1809337011300.

Find LCM of 921,867,780,675,581 with Prime Factorization

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

3 x 5 x 307 x 289 x 52 x 45 x 581 = 1809337011300

Therefore, the lowest common multiple of 921,867,780,675,581 is 1809337011300.

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.

921 x 867 x 780 x 675 x 581 = 244260496525500

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.

921 : 1, 3, 307, 921

867 : 1, 3, 17, 51, 289, 867

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,867,780,675,581, is 1.

Now, the common factors can be found like this.

921:3x 307

867:3x 17x 17

780:2x 2x 3x 5x 13

675:3x 3x 3x 5x 5

581:7x 83

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

3x 3x 3x 5 = 135

Therefore, the value for common factors is 135.

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 = 244260496525500/(1x135)

LCM = 244260496525500/135

LCM = 1809337011300

Thus, we can understand that the LCM of 921,867,780,675,581 is 1809337011300.
