Given numbers are 194,670,780,591,645

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

The LCM of 194,670,780,591,645 is 42941362620.

Find LCM of 194,670,780,591,645 with Prime Factorization

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

2 x 3 x 5 x 97 x 67 x 26 x 197 x 43 = 42941362620

Therefore, the lowest common multiple of 194,670,780,591,645 is 42941362620.

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.

194 x 670 x 780 x 591 x 645 = 38647226358000

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.

194 : 1, 2, 97, 194

670 : 1, 2, 5, 10, 67, 134, 335, 670

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

591 : 1, 3, 197, 591

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,670,780,591,645, is 1.

Now, the common factors can be found like this.

194:2x 97

670:2x 5x 67

780:2x 2x 3x 5x 13

591:3x 197

645:3x 5x 43

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 3x 3x 5x 5 = 900

Therefore, the value for common factors is 900.

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 = 38647226358000/(1x900)

LCM = 38647226358000/900

LCM = 42941362620

Thus, we can understand that the LCM of 194,670,780,591,645 is 42941362620.
