Given numbers are 344,781,355,478

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

The LCM of 344,781,355,478 is 321053480.

Find LCM of 344,781,355,478 with Prime Factorization

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

2 x 71 x 172 x 11 x 5 x 239 = 321053480

Therefore, the lowest common multiple of 344,781,355,478 is 321053480.

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.

344 x 781 x 355 x 478 = 45589594160

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.

344 : 1, 2, 4, 8, 43, 86, 172, 344

781 : 1, 11, 71, 781

355 : 1, 5, 71, 355

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,781,355,478, is 1.

Now, the common factors can be found like this.

344:2x 2x 2x 43

781:11x 71

355:5x 71

478:2x 239

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

2x 71 = 142

Therefore, the value for common factors is 142.

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 = 45589594160/(1x142)

LCM = 45589594160/142

LCM = 321053480

Thus, we can understand that the LCM of 344,781,355,478 is 321053480.
