Calculate the LCM of 872,395,642,363

Given numbers are 872,395,642,363

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

The LCM of 872,395,642,363 is 13378394040.

Find LCM of 872,395,642,363 with Prime Factorization


2 872, 395, 642, 363
3 436, 395, 321, 363
436, 395, 107, 121

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

2 x 3 x 436 x 395 x 107 x 121 = 13378394040

Therefore, the lowest common multiple of 872,395,642,363 is 13378394040.

LCM Formula to Find Lowest Common Multiple of 872,395,642,363

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.

872 x 395 x 642 x 363 = 80270364240

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

395 : 1, 5, 79, 395

642 : 1, 2, 3, 6, 107, 214, 321, 642

363 : 1, 3, 11, 33, 121, 363

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,395,642,363, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

395:5x 79

642:2x 3x 107

363:3x 11x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 80270364240/(1x6)

LCM = 80270364240/6

LCM = 13378394040

Thus, we can understand that the LCM of 872,395,642,363 is 13378394040.
