Given numbers are 328,586,643,124,990

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

The LCM of 328,586,643,124,990 is 948242310840.

Find LCM of 328,586,643,124,990 with Prime Factorization

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

2 x 2 x 82 x 293 x 643 x 31 x 495 = 948242310840

Therefore, the lowest common multiple of 328,586,643,124,990 is 948242310840.

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.

328 x 586 x 643 x 124 x 990 = 15171876973440

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.

328 : 1, 2, 4, 8, 41, 82, 164, 328

586 : 1, 2, 293, 586

643 : 1, 643

124 : 1, 2, 4, 31, 62, 124

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,586,643,124,990, is 1.

Now, the common factors can be found like this.

328:2x 2x 2x 41

586:2x 293

643:643

124:2x 2x 31

990:2x 3x 3x 5x 11

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 2 = 16

Therefore, the value for common factors is 16.

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 = 15171876973440/(1x16)

LCM = 15171876973440/16

LCM = 948242310840

Thus, we can understand that the LCM of 328,586,643,124,990 is 948242310840.
