Given numbers are 311,772,422,397

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

The LCM of 311,772,422,397 is 20111786564.

Find LCM of 311,772,422,397 with Prime Factorization

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

2 x 311 x 386 x 211 x 397 = 20111786564

Therefore, the lowest common multiple of 311,772,422,397 is 20111786564.

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 772 x 422 x 397 = 40223573128

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

772 : 1, 2, 4, 193, 386, 772

422 : 1, 2, 211, 422

397 : 1, 397

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,772,422,397, is 1.

Now, the common factors can be found like this.

311:311

772:2x 2x 193

422:2x 211

397:397

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 = 40223573128/(1x2)

LCM = 40223573128/2

LCM = 20111786564

Thus, we can understand that the LCM of 311,772,422,397 is 20111786564.
