Given numbers are 638,863,319,402

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

The LCM of 638,863,319,402 is 110669394.

Find LCM of 638,863,319,402 with Prime Factorization

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

2 x 11 x 29 x 1 x 863 x 1 x 201 = 110669394

Therefore, the lowest common multiple of 638,863,319,402 is 110669394.

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 319 x 402 = 70607073372

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

319 : 1, 11, 29, 319

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,863,319,402, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

863:863

319:11x 29

402:2x 3x 67

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

2x 11x 29 = 638

Therefore, the value for common factors is 638.

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 = 70607073372/(1x638)

LCM = 70607073372/638

LCM = 110669394

Thus, we can understand that the LCM of 638,863,319,402 is 110669394.
