Given numbers are 637,413,689,161,395

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

The LCM of 637,413,689,161,395 is 18096402415.

Find LCM of 637,413,689,161,395 with Prime Factorization

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

7 x 13 x 7 x 59 x 53 x 23 x 395 = 18096402415

Therefore, the lowest common multiple of 637,413,689,161,395 is 18096402415.

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 413 x 689 x 161 x 395 = 11527408338355

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

413 : 1, 7, 59, 413

689 : 1, 13, 53, 689

161 : 1, 7, 23, 161

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,413,689,161,395, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

413:7x 59

689:13x 53

161:7x 23

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.

7x 7x 13 = 637

Therefore, the value for common factors is 637.

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 = 11527408338355/(1x637)

LCM = 11527408338355/637

LCM = 18096402415

Thus, we can understand that the LCM of 637,413,689,161,395 is 18096402415.
