Given numbers are 338,491,337,638

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

The LCM of 338,491,337,638 is 17840982874.

Find LCM of 338,491,337,638 with Prime Factorization

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

2 x 169 x 491 x 337 x 319 = 17840982874

Therefore, the lowest common multiple of 338,491,337,638 is 17840982874.

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 491 x 337 x 638 = 35681965748

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

491 : 1, 491

337 : 1, 337

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 338,491,337,638, is 1.

Now, the common factors can be found like this.

338:2x 13x 13

491:491

337:337

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.

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 = 35681965748/(1x2)

LCM = 35681965748/2

LCM = 17840982874

Thus, we can understand that the LCM of 338,491,337,638 is 17840982874.
