Given numbers are 408,349,626,421

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

The LCM of 408,349,626,421 is 18763421016.

Find LCM of 408,349,626,421 with Prime Factorization

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

2 x 204 x 349 x 313 x 421 = 18763421016

Therefore, the lowest common multiple of 408,349,626,421 is 18763421016.

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.

408 x 349 x 626 x 421 = 37526842032

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.

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

349 : 1, 349

626 : 1, 2, 313, 626

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,349,626,421, is 1.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

349:349

626:2x 313

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 37526842032/(1x2)

LCM = 37526842032/2

LCM = 18763421016

Thus, we can understand that the LCM of 408,349,626,421 is 18763421016.
