Given numbers are 855,219,656,618

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

The LCM of 855,219,656,618 is 4217256720.

Find LCM of 855,219,656,618 with Prime Factorization

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

2 x 3 x 285 x 73 x 328 x 103 = 4217256720

Therefore, the lowest common multiple of 855,219,656,618 is 4217256720.

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.

855 x 219 x 656 x 618 = 75910620960

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.

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

219 : 1, 3, 73, 219

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

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,219,656,618, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

219:3x 73

656:2x 2x 2x 2x 41

618:2x 3x 103

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 75910620960/(1x18)

LCM = 75910620960/18

LCM = 4217256720

Thus, we can understand that the LCM of 855,219,656,618 is 4217256720.
