Given numbers are 257,731,323,559,440

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

The LCM of 257,731,323,559,440 is 20417385560.

Find LCM of 257,731,323,559,440 with Prime Factorization

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

17 x 43 x 257 x 1 x 19 x 13 x 440 = 20417385560

Therefore, the lowest common multiple of 257,731,323,559,440 is 20417385560.

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 731 x 323 x 559 x 440 = 14925108844360

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

731 : 1, 17, 43, 731

323 : 1, 17, 19, 323

559 : 1, 13, 43, 559

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,731,323,559,440, is 1.

Now, the common factors can be found like this.

257:257

731:17x 43

323:17x 19

559:13x 43

440:2x 2x 2x 5x 11

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

17x 43 = 731

Therefore, the value for common factors is 731.

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 = 14925108844360/(1x731)

LCM = 14925108844360/731

LCM = 20417385560

Thus, we can understand that the LCM of 257,731,323,559,440 is 20417385560.
