Given numbers are 780,910,164,388,641

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

The LCM of 780,910,164,388,641 is 13918943220.

Find LCM of 780,910,164,388,641 with Prime Factorization

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

2 x 2 x 5 x 13 x 3 x 7 x 41 x 97 x 641 = 13918943220

Therefore, the lowest common multiple of 780,910,164,388,641 is 13918943220.

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 910 x 164 x 388 x 641 = 28951401897600

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

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

164 : 1, 2, 4, 41, 82, 164

388 : 1, 2, 4, 97, 194, 388

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,910,164,388,641, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

910:2x 5x 7x 13

164:2x 2x 41

388:2x 2x 97

641:641

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 5x 13 = 2080

Therefore, the value for common factors is 2080.

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 = 28951401897600/(1x2080)

LCM = 28951401897600/2080

LCM = 13918943220

Thus, we can understand that the LCM of 780,910,164,388,641 is 13918943220.
