Given numbers are 781,411,247,770

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

The LCM of 781,411,247,770 is 5549934390.

Find LCM of 781,411,247,770 with Prime Factorization

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

11 x 71 x 411 x 247 x 70 = 5549934390

Therefore, the lowest common multiple of 781,411,247,770 is 5549934390.

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 411 x 247 x 770 = 61049278290

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

411 : 1, 3, 137, 411

247 : 1, 13, 19, 247

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,411,247,770, is 1.

Now, the common factors can be found like this.

781:11x 71

411:3x 137

247:13x 19

770:2x 5x 7x 11

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 = 61049278290/(1x11)

LCM = 61049278290/11

LCM = 5549934390

Thus, we can understand that the LCM of 781,411,247,770 is 5549934390.
