Given numbers are 542,491,785,813

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

The LCM of 542,491,785,813 is 626717310.

Find LCM of 542,491,785,813 with Prime Factorization

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

271 x 2 x 491 x 785 x 3 = 626717310

Therefore, the lowest common multiple of 542,491,785,813 is 626717310.

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.

542 x 491 x 785 x 813 = 169840391010

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.

542 : 1, 2, 271, 542

491 : 1, 491

785 : 1, 5, 157, 785

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,491,785,813, is 1.

Now, the common factors can be found like this.

542:2x 271

491:491

785:5x 157

813:3x 271

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

271 = 271

Therefore, the value for common factors is 271.

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 = 169840391010/(1x271)

LCM = 169840391010/271

LCM = 626717310

Thus, we can understand that the LCM of 542,491,785,813 is 626717310.
