Calculate the LCM of 855,689,920,599,395

Given numbers are 855,689,920,599,395

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

The LCM of 855,689,920,599,395 is 5129287867080.

Find LCM of 855,689,920,599,395 with Prime Factorization


5 855, 689, 920, 599, 395
171, 689, 184, 599, 79

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

5 x 171 x 689 x 184 x 599 x 79 = 5129287867080

Therefore, the lowest common multiple of 855,689,920,599,395 is 5129287867080.

LCM Formula to Find Lowest Common Multiple of 855,689,920,599,395

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.

855 x 689 x 920 x 599 x 395 = 128232196677000

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

689 : 1, 13, 53, 689

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

599 : 1, 599

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,689,920,599,395, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

689:13x 53

920:2x 2x 2x 5x 23

599:599

395:5x 79

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 128232196677000/(1x25)

LCM = 128232196677000/25

LCM = 5129287867080

Thus, we can understand that the LCM of 855,689,920,599,395 is 5129287867080.
