Given numbers are 780,572,940,235,856

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

The LCM of 780,572,940,235,856 is 86297640.

Find LCM of 780,572,940,235,856 with Prime Factorization

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

2 x 2 x 5 x 13 x 47 x 3 x 11 x 1 x 1 x 214 = 86297640

Therefore, the lowest common multiple of 780,572,940,235,856 is 86297640.

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 572 x 940 x 235 x 856 = 84364572864000

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

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

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

235 : 1, 5, 47, 235

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,572,940,235,856, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

572:2x 2x 11x 13

940:2x 2x 5x 47

235:5x 47

856:2x 2x 2x 107

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 2x 2x 5x 5x 13x 47 = 977600

Therefore, the value for common factors is 977600.

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 = 84364572864000/(1x977600)

LCM = 84364572864000/977600

LCM = 86297640

Thus, we can understand that the LCM of 780,572,940,235,856 is 86297640.
