Given numbers are 257,909,685,257

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

The LCM of 257,909,685,257 is 160024905.

Find LCM of 257,909,685,257 with Prime Factorization

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

257 x 1 x 909 x 685 x 1 = 160024905

Therefore, the lowest common multiple of 257,909,685,257 is 160024905.

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 909 x 685 x 257 = 41126400585

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

909 : 1, 3, 9, 101, 303, 909

685 : 1, 5, 137, 685

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,909,685,257, is 1.

Now, the common factors can be found like this.

257:257

909:3x 3x 101

685:5x 137

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.

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 = 41126400585/(1x257)

LCM = 41126400585/257

LCM = 160024905

Thus, we can understand that the LCM of 257,909,685,257 is 160024905.
