Given numbers are 668,914,981,656,560

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

The LCM of 668,914,981,656,560 is 1718990839440.

Find LCM of 668,914,981,656,560 with Prime Factorization

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

2 x 2 x 2 x 2 x 167 x 457 x 981 x 41 x 35 = 1718990839440

Therefore, the lowest common multiple of 668,914,981,656,560 is 1718990839440.

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.

668 x 914 x 981 x 656 x 560 = 220030827448320

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.

668 : 1, 2, 4, 167, 334, 668

914 : 1, 2, 457, 914

981 : 1, 3, 9, 109, 327, 981

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,914,981,656,560, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

914:2x 457

981:3x 3x 109

656:2x 2x 2x 2x 41

560:2x 2x 2x 2x 5x 7

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 2 = 128

Therefore, the value for common factors is 128.

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 = 220030827448320/(1x128)

LCM = 220030827448320/128

LCM = 1718990839440

Thus, we can understand that the LCM of 668,914,981,656,560 is 1718990839440.
