Given numbers are 311,865,138,454

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

The LCM of 311,865,138,454 is 8427163890.

Find LCM of 311,865,138,454 with Prime Factorization

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

2 x 311 x 865 x 69 x 227 = 8427163890

Therefore, the lowest common multiple of 311,865,138,454 is 8427163890.

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 138 x 454 = 16854327780

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,865,138,454, is 1.

Now, the common factors can be found like this.

311:311

865:5x 173

138:2x 3x 23

454:2x 227

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

2 = 2

Therefore, the value for common factors is 2.

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 = 16854327780/(1x2)

LCM = 16854327780/2

LCM = 8427163890

Thus, we can understand that the LCM of 311,865,138,454 is 8427163890.
