Given numbers are 855,642,698,451

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

The LCM of 855,642,698,451 is 28799295030.

Find LCM of 855,642,698,451 with Prime Factorization

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

2 x 3 x 285 x 107 x 349 x 451 = 28799295030

Therefore, the lowest common multiple of 855,642,698,451 is 28799295030.

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 642 x 698 x 451 = 172795770180

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

698 : 1, 2, 349, 698

451 : 1, 11, 41, 451

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,642,698,451, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

642:2x 3x 107

698:2x 349

451:11x 41

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 172795770180/(1x6)

LCM = 172795770180/6

LCM = 28799295030

Thus, we can understand that the LCM of 855,642,698,451 is 28799295030.
