Given numbers are 813,503,642,517

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

The LCM of 813,503,642,517 is 45244193082.

Find LCM of 813,503,642,517 with Prime Factorization

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

3 x 271 x 503 x 214 x 517 = 45244193082

Therefore, the lowest common multiple of 813,503,642,517 is 45244193082.

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.

813 x 503 x 642 x 517 = 135732579246

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.

813 : 1, 3, 271, 813

503 : 1, 503

642 : 1, 2, 3, 6, 107, 214, 321, 642

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,503,642,517, is 1.

Now, the common factors can be found like this.

813:3x 271

503:503

642:2x 3x 107

517:11x 47

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

3 = 3

Therefore, the value for common factors is 3.

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 = 135732579246/(1x3)

LCM = 135732579246/3

LCM = 45244193082

Thus, we can understand that the LCM of 813,503,642,517 is 45244193082.
