Calculate the LCM of 638,791,837,897,843

Given numbers are 638,791,837,897,843

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

The LCM of 638,791,837,897,843 is 35489520240174.

Find LCM of 638,791,837,897,843 with Prime Factorization


3 638, 791, 837, 897, 843
638, 791, 279, 299, 281

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

3 x 638 x 791 x 279 x 299 x 281 = 35489520240174

Therefore, the lowest common multiple of 638,791,837,897,843 is 35489520240174.

LCM Formula to Find Lowest Common Multiple of 638,791,837,897,843

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 791 x 837 x 897 x 843 = 319405682161566

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

791 : 1, 7, 113, 791

837 : 1, 3, 9, 27, 31, 93, 279, 837

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

843 : 1, 3, 281, 843

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,791,837,897,843, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

791:7x 113

837:3x 3x 3x 31

897:3x 13x 23

843:3x 281

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 319405682161566/(1x9)

LCM = 319405682161566/9

LCM = 35489520240174

Thus, we can understand that the LCM of 638,791,837,897,843 is 35489520240174.
