Given numbers are 641,340,780,910,604

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

The LCM of 641,340,780,910,604 is 8984140620.

Find LCM of 641,340,780,910,604 with Prime Factorization

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

2 x 2 x 5 x 13 x 641 x 17 x 3 x 7 x 151 = 8984140620

Therefore, the lowest common multiple of 641,340,780,910,604 is 8984140620.

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.

641 x 340 x 780 x 910 x 604 = 93435062448000

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.

641 : 1, 641

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

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

604 : 1, 2, 4, 151, 302, 604

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,340,780,910,604, is 1.

Now, the common factors can be found like this.

641:641

340:2x 2x 5x 17

780:2x 2x 3x 5x 13

910:2x 5x 7x 13

604:2x 2x 151

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 5x 13 = 10400

Therefore, the value for common factors is 10400.

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 = 93435062448000/(1x10400)

LCM = 93435062448000/10400

LCM = 8984140620

Thus, we can understand that the LCM of 641,340,780,910,604 is 8984140620.
