Given numbers are 798,656,438,726,855

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

The LCM of 798,656,438,726,855 is 34679771280.

Find LCM of 798,656,438,726,855 with Prime Factorization

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

2 x 3 x 19 x 7 x 328 x 73 x 121 x 15 = 34679771280

Therefore, the lowest common multiple of 798,656,438,726,855 is 34679771280.

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.

798 x 656 x 438 x 726 x 855 = 142325781333120

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

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

438 : 1, 2, 3, 6, 73, 146, 219, 438

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,656,438,726,855, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

656:2x 2x 2x 2x 41

438:2x 3x 73

726:2x 3x 11x 11

855:3x 3x 5x 19

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 3x 3x 3x 19 = 4104

Therefore, the value for common factors is 4104.

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 = 142325781333120/(1x4104)

LCM = 142325781333120/4104

LCM = 34679771280

Thus, we can understand that the LCM of 798,656,438,726,855 is 34679771280.
