Calculate the LCM of 638,819,187,897

Given numbers are 638,819,187,897

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

The LCM of 638,819,187,897 is 204306102.

Find LCM of 638,819,187,897 with Prime Factorization


3 638, 819, 187, 897
11 638, 273, 187, 299
13 58, 273, 17, 299
58, 21, 17, 23

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

3 x 11 x 13 x 58 x 21 x 17 x 23 = 204306102

Therefore, the lowest common multiple of 638,819,187,897 is 204306102.

LCM Formula to Find Lowest Common Multiple of 638,819,187,897

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.

638 x 819 x 187 x 897 = 87647317758

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.

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

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

187 : 1, 11, 17, 187

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,819,187,897, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

819:3x 3x 7x 13

187:11x 17

897:3x 13x 23

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

3x 11x 13 = 429

Therefore, the value for common factors is 429.

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 = 87647317758/(1x429)

LCM = 87647317758/429

LCM = 204306102

Thus, we can understand that the LCM of 638,819,187,897 is 204306102.
