Given numbers are 311,865,311,813

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

The LCM of 311,865,311,813 is 218709195.

Find LCM of 311,865,311,813 with Prime Factorization

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

311 x 1 x 865 x 1 x 813 = 218709195

Therefore, the lowest common multiple of 311,865,311,813 is 218709195.

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.

311 x 865 x 311 x 813 = 68018559645

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.

311 : 1, 311

865 : 1, 5, 173, 865

311 : 1, 311

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,865,311,813, is 1.

Now, the common factors can be found like this.

311:311

865:5x 173

311:311

813:3x 271

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

311 = 311

Therefore, the value for common factors is 311.

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 = 68018559645/(1x311)

LCM = 68018559645/311

LCM = 218709195

Thus, we can understand that the LCM of 311,865,311,813 is 218709195.
