Given numbers are 621,885,472,439

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

The LCM of 621,885,472,439 is 643380840.

Find LCM of 621,885,472,439 with Prime Factorization

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

3 x 59 x 207 x 5 x 8 x 439 = 643380840

Therefore, the lowest common multiple of 621,885,472,439 is 643380840.

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.

621 x 885 x 472 x 439 = 113878408680

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

885 : 1, 3, 5, 15, 59, 177, 295, 885

472 : 1, 2, 4, 8, 59, 118, 236, 472

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,885,472,439, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

885:3x 5x 59

472:2x 2x 2x 59

439:439

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

3x 59 = 177

Therefore, the value for common factors is 177.

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 = 113878408680/(1x177)

LCM = 113878408680/177

LCM = 643380840

Thus, we can understand that the LCM of 621,885,472,439 is 643380840.
