Given numbers are 781,891,242,352,740

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

The LCM of 781,891,242,352,740 is 4119556320.

Find LCM of 781,891,242,352,740 with Prime Factorization

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

2 x 2 x 11 x 71 x 81 x 11 x 8 x 185 = 4119556320

Therefore, the lowest common multiple of 781,891,242,352,740 is 4119556320.

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 891 x 242 x 352 x 740 = 43865035695360

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

242 : 1, 2, 11, 22, 121, 242

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,891,242,352,740, is 1.

Now, the common factors can be found like this.

781:11x 71

891:3x 3x 3x 3x 11

242:2x 11x 11

352:2x 2x 2x 2x 2x 11

740:2x 2x 5x 37

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

2x 2x 2x 11x 11x 11 = 10648

Therefore, the value for common factors is 10648.

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 = 43865035695360/(1x10648)

LCM = 43865035695360/10648

LCM = 4119556320

Thus, we can understand that the LCM of 781,891,242,352,740 is 4119556320.
