Given numbers are 780,519,402,939,618

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

The LCM of 780,519,402,939,618 is 291472154220.

Find LCM of 780,519,402,939,618 with Prime Factorization

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

2 x 3 x 130 x 173 x 67 x 313 x 103 = 291472154220

Therefore, the lowest common multiple of 780,519,402,939,618 is 291472154220.

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.

780 x 519 x 402 x 939 x 618 = 94436977967280

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.

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

519 : 1, 3, 173, 519

402 : 1, 2, 3, 6, 67, 134, 201, 402

939 : 1, 3, 313, 939

618 : 1, 2, 3, 6, 103, 206, 309, 618

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,519,402,939,618, is 3.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

519:3x 173

402:2x 3x 67

939:3x 313

618:2x 3x 103

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 3 = 108

Therefore, the value for common factors is 108.

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 = 94436977967280/(3x108)

LCM = 94436977967280/324

LCM = 291472154220

Thus, we can understand that the LCM of 780,519,402,939,618 is 291472154220.
