Given numbers are 682,338,252,168,638

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

The LCM of 682,338,252,168,638 is 842305464.

Find LCM of 682,338,252,168,638 with Prime Factorization

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

2 x 2 x 3 x 7 x 11 x 31 x 169 x 3 x 2 x 29 = 842305464

Therefore, the lowest common multiple of 682,338,252,168,638 is 842305464.

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.

682 x 338 x 252 x 168 x 638 = 6226321989888

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.

682 : 1, 2, 11, 22, 31, 62, 341, 682

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

252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,338,252,168,638, is 2.

Now, the common factors can be found like this.

682:2x 11x 31

338:2x 13x 13

252:2x 2x 3x 3x 7

168:2x 2x 2x 3x 7

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 2x 2x 2x 3x 7x 11 = 3696

Therefore, the value for common factors is 3696.

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 = 6226321989888/(2x3696)

LCM = 6226321989888/7392

LCM = 842305464

Thus, we can understand that the LCM of 682,338,252,168,638 is 842305464.
