Given numbers are 781,517,707,871

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

The LCM of 781,517,707,871 is 22604060479.

Find LCM of 781,517,707,871 with Prime Factorization

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

11 x 71 x 47 x 707 x 871 = 22604060479

Therefore, the lowest common multiple of 781,517,707,871 is 22604060479.

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.

781 x 517 x 707 x 871 = 248644665269

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.

781 : 1, 11, 71, 781

517 : 1, 11, 47, 517

707 : 1, 7, 101, 707

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,517,707,871, is 1.

Now, the common factors can be found like this.

781:11x 71

517:11x 47

707:7x 101

871:13x 67

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

11 = 11

Therefore, the value for common factors is 11.

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 = 248644665269/(1x11)

LCM = 248644665269/11

LCM = 22604060479

Thus, we can understand that the LCM of 781,517,707,871 is 22604060479.
