Given numbers are 638,338,858,130

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

The LCM of 638,338,858,130 is 1617330.

Find LCM of 638,338,858,130 with Prime Factorization

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

2 x 11 x 13 x 29 x 13 x 3 x 5 = 1617330

Therefore, the lowest common multiple of 638,338,858,130 is 1617330.

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 338 x 858 x 130 = 24052931760

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

338 : 1, 2, 13, 26, 169, 338

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,338,858,130, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

338:2x 13x 13

858:2x 3x 11x 13

130:2x 5x 13

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 11x 13x 13 = 7436

Therefore, the value for common factors is 7436.

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 = 24052931760/(2x7436)

LCM = 24052931760/14872

LCM = 1617330

Thus, we can understand that the LCM of 638,338,858,130 is 1617330.
