Given numbers are 538,580,491,394

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

The LCM of 538,580,491,394 is 15091346540.

Find LCM of 538,580,491,394 with Prime Factorization

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

2 x 269 x 290 x 491 x 197 = 15091346540

Therefore, the lowest common multiple of 538,580,491,394 is 15091346540.

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.

538 x 580 x 491 x 394 = 60365386160

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.

538 : 1, 2, 269, 538

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

491 : 1, 491

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,580,491,394, is 1.

Now, the common factors can be found like this.

538:2x 269

580:2x 2x 5x 29

491:491

394:2x 197

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 = 60365386160/(1x4)

LCM = 60365386160/4

LCM = 15091346540

Thus, we can understand that the LCM of 538,580,491,394 is 15091346540.
