Given numbers are 855,218,418,698

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

The LCM of 855,218,418,698 is 715551210.

Find LCM of 855,218,418,698 with Prime Factorization

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

2 x 19 x 45 x 109 x 11 x 349 = 715551210

Therefore, the lowest common multiple of 855,218,418,698 is 715551210.

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 218 x 418 x 698 = 54381891960

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

218 : 1, 2, 109, 218

418 : 1, 2, 11, 19, 22, 38, 209, 418

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,218,418,698, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

218:2x 109

418:2x 11x 19

698:2x 349

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 19 = 76

Therefore, the value for common factors is 76.

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 = 54381891960/(1x76)

LCM = 54381891960/76

LCM = 715551210

Thus, we can understand that the LCM of 855,218,418,698 is 715551210.
