Given numbers are 517,518,258,781

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

The LCM of 517,518,258,781 is 2452835154.

Find LCM of 517,518,258,781 with Prime Factorization

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

2 x 11 x 47 x 259 x 129 x 71 = 2452835154

Therefore, the lowest common multiple of 517,518,258,781 is 2452835154.

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 518 x 258 x 781 = 53962373388

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

518 : 1, 2, 7, 14, 37, 74, 259, 518

258 : 1, 2, 3, 6, 43, 86, 129, 258

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,518,258,781, is 1.

Now, the common factors can be found like this.

517:11x 47

518:2x 7x 37

258:2x 3x 43

781:11x 71

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 = 53962373388/(1x22)

LCM = 53962373388/22

LCM = 2452835154

Thus, we can understand that the LCM of 517,518,258,781 is 2452835154.
