Given numbers are 638,828,858,806

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

The LCM of 638,828,858,806 is 106445196.

Find LCM of 638,828,858,806 with Prime Factorization

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

2 x 3 x 11 x 13 x 29 x 138 x 1 x 31 = 106445196

Therefore, the lowest common multiple of 638,828,858,806 is 106445196.

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.

638 x 828 x 858 x 806 = 365319912672

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

806 : 1, 2, 13, 26, 31, 62, 403, 806

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,828,858,806, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

828:2x 2x 3x 3x 23

858:2x 3x 11x 13

806:2x 13x 31

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 3x 11x 13 = 1716

Therefore, the value for common factors is 1716.

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 = 365319912672/(2x1716)

LCM = 365319912672/3432

LCM = 106445196

Thus, we can understand that the LCM of 638,828,858,806 is 106445196.
