Given numbers are 771,165,681,257

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

The LCM of 771,165,681,257 is 9625935.

Find LCM of 771,165,681,257 with Prime Factorization

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

3 x 257 x 1 x 55 x 227 x 1 = 9625935

Therefore, the lowest common multiple of 771,165,681,257 is 9625935.

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.

771 x 165 x 681 x 257 = 22264787655

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.

771 : 1, 3, 257, 771

165 : 1, 3, 5, 11, 15, 33, 55, 165

681 : 1, 3, 227, 681

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,165,681,257, is 1.

Now, the common factors can be found like this.

771:3x 257

165:3x 5x 11

681:3x 227

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.

3x 3x 257 = 2313

Therefore, the value for common factors is 2313.

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 = 22264787655/(1x2313)

LCM = 22264787655/2313

LCM = 9625935

Thus, we can understand that the LCM of 771,165,681,257 is 9625935.
