Given numbers are 521,521,731,257

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

The LCM of 521,521,731,257 is 97878707.

Find LCM of 521,521,731,257 with Prime Factorization

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

521 x 1 x 1 x 731 x 257 = 97878707

Therefore, the lowest common multiple of 521,521,731,257 is 97878707.

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.

521 x 521 x 731 x 257 = 50994806347

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.

521 : 1, 521

521 : 1, 521

731 : 1, 17, 43, 731

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,521,731,257, is 1.

Now, the common factors can be found like this.

521:521

521:521

731:17x 43

257:257

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

521 = 521

Therefore, the value for common factors is 521.

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 = 50994806347/(1x521)

LCM = 50994806347/521

LCM = 97878707

Thus, we can understand that the LCM of 521,521,731,257 is 97878707.
