Given numbers are 381,245,478,638

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

The LCM of 381,245,478,638 is 14233432290.

Find LCM of 381,245,478,638 with Prime Factorization

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

2 x 381 x 245 x 239 x 319 = 14233432290

Therefore, the lowest common multiple of 381,245,478,638 is 14233432290.

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.

381 x 245 x 478 x 638 = 28466864580

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.

381 : 1, 3, 127, 381

245 : 1, 5, 7, 35, 49, 245

478 : 1, 2, 239, 478

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,245,478,638, is 1.

Now, the common factors can be found like this.

381:3x 127

245:5x 7x 7

478:2x 239

638:2x 11x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 28466864580/(1x2)

LCM = 28466864580/2

LCM = 14233432290

Thus, we can understand that the LCM of 381,245,478,638 is 14233432290.
