Given numbers are 638,319,529,445

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

The LCM of 638,319,529,445 is 150188390.

Find LCM of 638,319,529,445 with Prime Factorization

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

11 x 29 x 2 x 1 x 529 x 445 = 150188390

Therefore, the lowest common multiple of 638,319,529,445 is 150188390.

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 319 x 529 x 445 = 47910096410

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

319 : 1, 11, 29, 319

529 : 1, 23, 529

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,319,529,445, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

319:11x 29

529:23x 23

445:5x 89

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

11x 29 = 319

Therefore, the value for common factors is 319.

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 = 47910096410/(1x319)

LCM = 47910096410/319

LCM = 150188390

Thus, we can understand that the LCM of 638,319,529,445 is 150188390.
