Given numbers are 115,368,781,538

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

The LCM of 115,368,781,538 is 386563760.

Find LCM of 115,368,781,538 with Prime Factorization

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

2 x 23 x 5 x 8 x 781 x 269 = 386563760

Therefore, the lowest common multiple of 115,368,781,538 is 386563760.

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.

115 x 368 x 781 x 538 = 17781932960

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.

115 : 1, 5, 23, 115

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

781 : 1, 11, 71, 781

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,368,781,538, is 1.

Now, the common factors can be found like this.

115:5x 23

368:2x 2x 2x 2x 23

781:11x 71

538:2x 269

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

2x 23 = 46

Therefore, the value for common factors is 46.

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 = 17781932960/(1x46)

LCM = 17781932960/46

LCM = 386563760

Thus, we can understand that the LCM of 115,368,781,538 is 386563760.
