Calculate the LCM of 809,897,381,381

Given numbers are 809,897,381,381

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

The LCM of 809,897,381,381 is 92160471.

Find LCM of 809,897,381,381 with Prime Factorization


3 809, 897, 381, 381
127 809, 299, 127, 127
809, 299, 1, 1

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

3 x 127 x 809 x 299 x 1 x 1 = 92160471

Therefore, the lowest common multiple of 809,897,381,381 is 92160471.

LCM Formula to Find Lowest Common Multiple of 809,897,381,381

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.

809 x 897 x 381 x 381 = 105339418353

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.

809 : 1, 809

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

381 : 1, 3, 127, 381

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,897,381,381, is 1.

Now, the common factors can be found like this.

809:809

897:3x 13x 23

381:3x 127

381:3x 127

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

3x 3x 127 = 1143

Therefore, the value for common factors is 1143.

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 = 105339418353/(1x1143)

LCM = 105339418353/1143

LCM = 92160471

Thus, we can understand that the LCM of 809,897,381,381 is 92160471.
