Given numbers are 782,218,405,317

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

The LCM of 782,218,405,317 is 10943280630.

Find LCM of 782,218,405,317 with Prime Factorization

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

2 x 391 x 109 x 405 x 317 = 10943280630

Therefore, the lowest common multiple of 782,218,405,317 is 10943280630.

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.

782 x 218 x 405 x 317 = 21886561260

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

218 : 1, 2, 109, 218

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

317 : 1, 317

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,218,405,317, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

218:2x 109

405:3x 3x 3x 3x 5

317:317

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

2 = 2

Therefore, the value for common factors is 2.

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 = 21886561260/(1x2)

LCM = 21886561260/2

LCM = 10943280630

Thus, we can understand that the LCM of 782,218,405,317 is 10943280630.
