Given numbers are 257,481,940,771

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

The LCM of 257,481,940,771 is 348599940.

Find LCM of 257,481,940,771 with Prime Factorization

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

257 x 1 x 481 x 940 x 3 = 348599940

Therefore, the lowest common multiple of 257,481,940,771 is 348599940.

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.

257 x 481 x 940 x 771 = 89590184580

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.

257 : 1, 257

481 : 1, 13, 37, 481

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,481,940,771, is 1.

Now, the common factors can be found like this.

257:257

481:13x 37

940:2x 2x 5x 47

771:3x 257

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

257 = 257

Therefore, the value for common factors is 257.

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 = 89590184580/(1x257)

LCM = 89590184580/257

LCM = 348599940

Thus, we can understand that the LCM of 257,481,940,771 is 348599940.
