Calculate the LCM of 858,507,891

Given numbers are 858,507,891

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

The LCM of 858,507,891 is 301158.

Find LCM of 858,507,891 with Prime Factorization


3 858, 507, 891
11 286, 169, 297
13 26, 169, 27
2, 13, 27

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

3 x 11 x 13 x 2 x 13 x 27 = 301158

Therefore, the lowest common multiple of 858,507,891 is 301158.

LCM Formula to Find Lowest Common Multiple of 858,507,891

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.

858 x 507 x 891 = 387590346

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.

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

507 : 1, 3, 13, 39, 169, 507

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,507,891, is 3.

Now, the common factors can be found like this.

858:2x 3x 11x 13

507:3x 13x 13

891:3x 3x 3x 3x 11

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 = 387590346/(3x429)

LCM = 387590346/1287

LCM = 301158

Thus, we can understand that the LCM of 858,507,891 is 301158.
