Given numbers are 638,863,506,691

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

The LCM of 638,863,506,691 is 8750590442.

Find LCM of 638,863,506,691 with Prime Factorization

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

2 x 11 x 29 x 863 x 23 x 691 = 8750590442

Therefore, the lowest common multiple of 638,863,506,691 is 8750590442.

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 863 x 506 x 691 = 192512989724

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

863 : 1, 863

506 : 1, 2, 11, 22, 23, 46, 253, 506

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,863,506,691, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

863:863

506:2x 11x 23

691:691

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 192512989724/(1x22)

LCM = 192512989724/22

LCM = 8750590442

Thus, we can understand that the LCM of 638,863,506,691 is 8750590442.
