Given numbers are 431,398,338,686

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

The LCM of 431,398,338,686 is 9943543246.

Find LCM of 431,398,338,686 with Prime Factorization

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

2 x 431 x 199 x 169 x 343 = 9943543246

Therefore, the lowest common multiple of 431,398,338,686 is 9943543246.

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.

431 x 398 x 338 x 686 = 39774172984

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.

431 : 1, 431

398 : 1, 2, 199, 398

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,398,338,686, is 1.

Now, the common factors can be found like this.

431:431

398:2x 199

338:2x 13x 13

686:2x 7x 7x 7

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 = 39774172984/(1x4)

LCM = 39774172984/4

LCM = 9943543246

Thus, we can understand that the LCM of 431,398,338,686 is 9943543246.
