Given numbers are 642,845,228,898

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

The LCM of 642,845,228,898 is 9255964380.

Find LCM of 642,845,228,898 with Prime Factorization

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

2 x 3 x 107 x 845 x 38 x 449 = 9255964380

Therefore, the lowest common multiple of 642,845,228,898 is 9255964380.

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.

642 x 845 x 228 x 898 = 111071572560

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.

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

845 : 1, 5, 13, 65, 169, 845

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,845,228,898, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

845:5x 13x 13

228:2x 2x 3x 19

898:2x 449

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 3 = 12

Therefore, the value for common factors is 12.

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 = 111071572560/(1x12)

LCM = 111071572560/12

LCM = 9255964380

Thus, we can understand that the LCM of 642,845,228,898 is 9255964380.
