Given numbers are 813,678,813,393

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

The LCM of 813,678,813,393 is 24069678.

Find LCM of 813,678,813,393 with Prime Factorization

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

3 x 271 x 1 x 226 x 1 x 131 = 24069678

Therefore, the lowest common multiple of 813,678,813,393 is 24069678.

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.

813 x 678 x 813 x 393 = 176117833926

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.

813 : 1, 3, 271, 813

678 : 1, 2, 3, 6, 113, 226, 339, 678

813 : 1, 3, 271, 813

393 : 1, 3, 131, 393

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,678,813,393, is 3.

Now, the common factors can be found like this.

813:3x 271

678:2x 3x 113

813:3x 271

393:3x 131

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 = 176117833926/(3x2439)

LCM = 176117833926/7317

LCM = 24069678

Thus, we can understand that the LCM of 813,678,813,393 is 24069678.
