Given numbers are 338,398,428,747

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

The LCM of 338,398,428,747 is 10752368796.

Find LCM of 338,398,428,747 with Prime Factorization

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

2 x 169 x 199 x 214 x 747 = 10752368796

Therefore, the lowest common multiple of 338,398,428,747 is 10752368796.

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.

338 x 398 x 428 x 747 = 43009475184

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.

338 : 1, 2, 13, 26, 169, 338

398 : 1, 2, 199, 398

428 : 1, 2, 4, 107, 214, 428

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,398,428,747, is 1.

Now, the common factors can be found like this.

338:2x 13x 13

398:2x 199

428:2x 2x 107

747:3x 3x 83

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 43009475184/(1x4)

LCM = 43009475184/4

LCM = 10752368796

Thus, we can understand that the LCM of 338,398,428,747 is 10752368796.
