Calculate the LCM of 637,170,561,845,656

Given numbers are 637,170,561,845,656

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

The LCM of 637,170,561,845,656 is 15237702480.

Find LCM of 637,170,561,845,656 with Prime Factorization


2 637, 170, 561, 845, 656
5 637, 85, 561, 845, 328
13 637, 17, 561, 169, 328
17 49, 17, 561, 13, 328
49, 1, 33, 13, 328

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

2 x 5 x 13 x 17 x 49 x 1 x 33 x 13 x 328 = 15237702480

Therefore, the lowest common multiple of 637,170,561,845,656 is 15237702480.

LCM Formula to Find Lowest Common Multiple of 637,170,561,845,656

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.

637 x 170 x 561 x 845 x 656 = 33675322480800

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.

637 : 1, 7, 13, 49, 91, 637

170 : 1, 2, 5, 10, 17, 34, 85, 170

561 : 1, 3, 11, 17, 33, 51, 187, 561

845 : 1, 5, 13, 65, 169, 845

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,170,561,845,656, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

170:2x 5x 17

561:3x 11x 17

845:5x 13x 13

656:2x 2x 2x 2x 41

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

2x 5x 13x 17 = 2210

Therefore, the value for common factors is 2210.

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 = 33675322480800/(1x2210)

LCM = 33675322480800/2210

LCM = 15237702480

Thus, we can understand that the LCM of 637,170,561,845,656 is 15237702480.
