Given numbers are 777,813,813,257

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

The LCM of 777,813,813,257 is 54115719.

Find LCM of 777,813,813,257 with Prime Factorization

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

3 x 271 x 259 x 1 x 1 x 257 = 54115719

Therefore, the lowest common multiple of 777,813,813,257 is 54115719.

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.

777 x 813 x 813 x 257 = 131988238641

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

813 : 1, 3, 271, 813

813 : 1, 3, 271, 813

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,813,813,257, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

813:3x 271

813:3x 271

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 271 = 2439

Therefore, the value for common factors is 2439.

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 = 131988238641/(1x2439)

LCM = 131988238641/2439

LCM = 54115719

Thus, we can understand that the LCM of 777,813,813,257 is 54115719.
