Given numbers are 830,394,394,972,618

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

The LCM of 830,394,394,972,618 is 8184983580.

Find LCM of 830,394,394,972,618 with Prime Factorization

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

2 x 3 x 197 x 415 x 1 x 1 x 162 x 103 = 8184983580

Therefore, the lowest common multiple of 830,394,394,972,618 is 8184983580.

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.

830 x 394 x 394 x 972 x 618 = 77397204732480

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.

830 : 1, 2, 5, 10, 83, 166, 415, 830

394 : 1, 2, 197, 394

394 : 1, 2, 197, 394

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,394,394,972,618, is 2.

Now, the common factors can be found like this.

830:2x 5x 83

394:2x 197

394:2x 197

972:2x 2x 3x 3x 3x 3x 3

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 2x 3x 197 = 4728

Therefore, the value for common factors is 4728.

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 = 77397204732480/(2x4728)

LCM = 77397204732480/9456

LCM = 8184983580

Thus, we can understand that the LCM of 830,394,394,972,618 is 8184983580.
