Given numbers are 388,890,205,788,780

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

The LCM of 388,890,205,788,780 is 54388417980.

Find LCM of 388,890,205,788,780 with Prime Factorization

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

2 x 2 x 5 x 97 x 89 x 41 x 197 x 39 = 54388417980

Therefore, the lowest common multiple of 388,890,205,788,780 is 54388417980.

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.

388 x 890 x 205 x 788 x 780 = 43510734384000

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.

388 : 1, 2, 4, 97, 194, 388

890 : 1, 2, 5, 10, 89, 178, 445, 890

205 : 1, 5, 41, 205

788 : 1, 2, 4, 197, 394, 788

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,890,205,788,780, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

890:2x 5x 89

205:5x 41

788:2x 2x 197

780:2x 2x 3x 5x 13

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

2x 2x 2x 2x 2x 5x 5 = 800

Therefore, the value for common factors is 800.

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 = 43510734384000/(1x800)

LCM = 43510734384000/800

LCM = 54388417980

Thus, we can understand that the LCM of 388,890,205,788,780 is 54388417980.
