Given numbers are 641,247,614,781,660

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

The LCM of 641,247,614,781,660 is 2277695388540.

Find LCM of 641,247,614,781,660 with Prime Factorization

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

2 x 11 x 641 x 247 x 307 x 71 x 30 = 2277695388540

Therefore, the lowest common multiple of 641,247,614,781,660 is 2277695388540.

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 247 x 614 x 781 x 660 = 50109298547880

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

247 : 1, 13, 19, 247

614 : 1, 2, 307, 614

781 : 1, 11, 71, 781

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,247,614,781,660, is 1.

Now, the common factors can be found like this.

641:641

247:13x 19

614:2x 307

781:11x 71

660:2x 2x 3x 5x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 50109298547880/(1x22)

LCM = 50109298547880/22

LCM = 2277695388540

Thus, we can understand that the LCM of 641,247,614,781,660 is 2277695388540.
