Given numbers are 261,417,691,857

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

The LCM of 261,417,691,857 is 21483952173.

Find LCM of 261,417,691,857 with Prime Factorization

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

3 x 87 x 139 x 691 x 857 = 21483952173

Therefore, the lowest common multiple of 261,417,691,857 is 21483952173.

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.

261 x 417 x 691 x 857 = 64451856519

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.

261 : 1, 3, 9, 29, 87, 261

417 : 1, 3, 139, 417

691 : 1, 691

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,417,691,857, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

417:3x 139

691:691

857:857

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

3 = 3

Therefore, the value for common factors is 3.

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 = 64451856519/(1x3)

LCM = 64451856519/3

LCM = 21483952173

Thus, we can understand that the LCM of 261,417,691,857 is 21483952173.
