Given numbers are 128,394,778,747,609

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

The LCM of 128,394,778,747,609 is 1487450208384.

Find LCM of 128,394,778,747,609 with Prime Factorization

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

2 x 3 x 64 x 197 x 389 x 249 x 203 = 1487450208384

Therefore, the lowest common multiple of 128,394,778,747,609 is 1487450208384.

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.

128 x 394 x 778 x 747 x 609 = 17849402500608

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

394 : 1, 2, 197, 394

778 : 1, 2, 389, 778

747 : 1, 3, 9, 83, 249, 747

609 : 1, 3, 7, 21, 29, 87, 203, 609

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,394,778,747,609, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

394:2x 197

778:2x 389

747:3x 3x 83

609:3x 7x 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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 17849402500608/(1x12)

LCM = 17849402500608/12

LCM = 1487450208384

Thus, we can understand that the LCM of 128,394,778,747,609 is 1487450208384.
