Given numbers are 780,394,754,652,910

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

The LCM of 780,394,754,652,910 is 5084455740.

Find LCM of 780,394,754,652,910 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 197 x 29 x 163 x 7 = 5084455740

Therefore, the lowest common multiple of 780,394,754,652,910 is 5084455740.

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 394 x 754 x 652 x 910 = 137483683209600

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

394 : 1, 2, 197, 394

754 : 1, 2, 13, 26, 29, 58, 377, 754

652 : 1, 2, 4, 163, 326, 652

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,394,754,652,910, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

394:2x 197

754:2x 13x 29

652:2x 2x 163

910:2x 5x 7x 13

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 5x 13x 13 = 13520

Therefore, the value for common factors is 13520.

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 = 137483683209600/(2x13520)

LCM = 137483683209600/27040

LCM = 5084455740

Thus, we can understand that the LCM of 780,394,754,652,910 is 5084455740.
