Given numbers are 436,558,401,638

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

The LCM of 436,558,401,638 is 15560578836.

Find LCM of 436,558,401,638 with Prime Factorization

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

2 x 218 x 279 x 401 x 319 = 15560578836

Therefore, the lowest common multiple of 436,558,401,638 is 15560578836.

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.

436 x 558 x 401 x 638 = 62242315344

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.

436 : 1, 2, 4, 109, 218, 436

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

401 : 1, 401

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 436,558,401,638, is 1.

Now, the common factors can be found like this.

436:2x 2x 109

558:2x 3x 3x 31

401:401

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.

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 = 62242315344/(1x4)

LCM = 62242315344/4

LCM = 15560578836

Thus, we can understand that the LCM of 436,558,401,638 is 15560578836.
