Given numbers are 638,826,568,863

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

The LCM of 638,826,568,863 is 64580271448.

Find LCM of 638,826,568,863 with Prime Factorization

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

2 x 319 x 413 x 284 x 863 = 64580271448

Therefore, the lowest common multiple of 638,826,568,863 is 64580271448.

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 826 x 568 x 863 = 258321085792

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

826 : 1, 2, 7, 14, 59, 118, 413, 826

568 : 1, 2, 4, 8, 71, 142, 284, 568

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,826,568,863, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

826:2x 7x 59

568:2x 2x 2x 71

863:863

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 258321085792/(1x4)

LCM = 258321085792/4

LCM = 64580271448

Thus, we can understand that the LCM of 638,826,568,863 is 64580271448.
