Given numbers are 311,646,803,638

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

The LCM of 311,646,803,638 is 4678498022.

Find LCM of 311,646,803,638 with Prime Factorization

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

2 x 11 x 311 x 323 x 73 x 29 = 4678498022

Therefore, the lowest common multiple of 311,646,803,638 is 4678498022.

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 646 x 803 x 638 = 102926956484

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

803 : 1, 11, 73, 803

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,646,803,638, is 1.

Now, the common factors can be found like this.

311:311

646:2x 17x 19

803:11x 73

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 102926956484/(1x22)

LCM = 102926956484/22

LCM = 4678498022

Thus, we can understand that the LCM of 311,646,803,638 is 4678498022.
