Given numbers are 517,286,861,838

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

The LCM of 517,286,861,838 is 4849322478.

Find LCM of 517,286,861,838 with Prime Factorization

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

2 x 11 x 47 x 13 x 861 x 419 = 4849322478

Therefore, the lowest common multiple of 517,286,861,838 is 4849322478.

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.

517 x 286 x 861 x 838 = 106685094516

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.

517 : 1, 11, 47, 517

286 : 1, 2, 11, 13, 22, 26, 143, 286

861 : 1, 3, 7, 21, 41, 123, 287, 861

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,286,861,838, is 1.

Now, the common factors can be found like this.

517:11x 47

286:2x 11x 13

861:3x 7x 41

838:2x 419

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 106685094516/(1x22)

LCM = 106685094516/22

LCM = 4849322478

Thus, we can understand that the LCM of 517,286,861,838 is 4849322478.
