Given numbers are 780,785,110,478,940

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

The LCM of 780,785,110,478,940 is 15131524980.

Find LCM of 780,785,110,478,940 with Prime Factorization

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

2 x 2 x 5 x 39 x 157 x 11 x 239 x 47 = 15131524980

Therefore, the lowest common multiple of 780,785,110,478,940 is 15131524980.

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 785 x 110 x 478 x 940 = 30263049960000

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

785 : 1, 5, 157, 785

110 : 1, 2, 5, 10, 11, 22, 55, 110

478 : 1, 2, 239, 478

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,785,110,478,940, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

785:5x 157

110:2x 5x 11

478:2x 239

940:2x 2x 5x 47

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 5x 5 = 2000

Therefore, the value for common factors is 2000.

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 = 30263049960000/(1x2000)

LCM = 30263049960000/2000

LCM = 15131524980

Thus, we can understand that the LCM of 780,785,110,478,940 is 15131524980.
