Given numbers are 257,691,507,621

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

The LCM of 257,691,507,621 is 18637578063.

Find LCM of 257,691,507,621 with Prime Factorization

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

3 x 257 x 691 x 169 x 207 = 18637578063

Therefore, the lowest common multiple of 257,691,507,621 is 18637578063.

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 691 x 507 x 621 = 55912734189

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

691 : 1, 691

507 : 1, 3, 13, 39, 169, 507

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,691,507,621, is 1.

Now, the common factors can be found like this.

257:257

691:691

507:3x 13x 13

621:3x 3x 3x 23

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 = 55912734189/(1x3)

LCM = 55912734189/3

LCM = 18637578063

Thus, we can understand that the LCM of 257,691,507,621 is 18637578063.
