Given numbers are 780,638,862,934

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

The LCM of 780,638,862,934 is 50081743140.

Find LCM of 780,638,862,934 with Prime Factorization

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

2 x 390 x 319 x 431 x 467 = 50081743140

Therefore, the lowest common multiple of 780,638,862,934 is 50081743140.

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.

780 x 638 x 862 x 934 = 400653945120

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.

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

862 : 1, 2, 431, 862

934 : 1, 2, 467, 934

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,638,862,934, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

638:2x 11x 29

862:2x 431

934:2x 467

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 400653945120/(2x4)

LCM = 400653945120/8

LCM = 50081743140

Thus, we can understand that the LCM of 780,638,862,934 is 50081743140.
