Given numbers are 381,782,857,418

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

The LCM of 381,782,857,418 is 53365285446.

Find LCM of 381,782,857,418 with Prime Factorization

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

2 x 381 x 391 x 857 x 209 = 53365285446

Therefore, the lowest common multiple of 381,782,857,418 is 53365285446.

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.

381 x 782 x 857 x 418 = 106730570892

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.

381 : 1, 3, 127, 381

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

857 : 1, 857

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,782,857,418, is 1.

Now, the common factors can be found like this.

381:3x 127

782:2x 17x 23

857:857

418:2x 11x 19

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 = 106730570892/(1x2)

LCM = 106730570892/2

LCM = 53365285446

Thus, we can understand that the LCM of 381,782,857,418 is 53365285446.
