Given numbers are 454,634,478,638

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

The LCM of 454,634,478,638 is 10972452238.

Find LCM of 454,634,478,638 with Prime Factorization

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

2 x 227 x 317 x 239 x 319 = 10972452238

Therefore, the lowest common multiple of 454,634,478,638 is 10972452238.

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.

454 x 634 x 478 x 638 = 87779617904

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.

454 : 1, 2, 227, 454

634 : 1, 2, 317, 634

478 : 1, 2, 239, 478

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,634,478,638, is 2.

Now, the common factors can be found like this.

454:2x 227

634:2x 317

478:2x 239

638:2x 11x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 87779617904/(2x4)

LCM = 87779617904/8

LCM = 10972452238

Thus, we can understand that the LCM of 454,634,478,638 is 10972452238.
