Given numbers are 638,813,854,258

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

The LCM of 638,813,854,258 is 9523740534.

Find LCM of 638,813,854,258 with Prime Factorization

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

2 x 3 x 319 x 271 x 427 x 43 = 9523740534

Therefore, the lowest common multiple of 638,813,854,258 is 9523740534.

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 813 x 854 x 258 = 114284886408

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

813 : 1, 3, 271, 813

854 : 1, 2, 7, 14, 61, 122, 427, 854

258 : 1, 2, 3, 6, 43, 86, 129, 258

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,813,854,258, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

813:3x 271

854:2x 7x 61

258:2x 3x 43

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 = 114284886408/(1x12)

LCM = 114284886408/12

LCM = 9523740534

Thus, we can understand that the LCM of 638,813,854,258 is 9523740534.
