Given numbers are 685,264,394,814,990

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

The LCM of 685,264,394,814,990 is 3954428280.

Find LCM of 685,264,394,814,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 137 x 4 x 197 x 37 x 3 = 3954428280

Therefore, the lowest common multiple of 685,264,394,814,990 is 3954428280.

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.

685 x 264 x 394 x 814 x 990 = 57418298625600

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.

685 : 1, 5, 137, 685

264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264

394 : 1, 2, 197, 394

814 : 1, 2, 11, 22, 37, 74, 407, 814

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 685,264,394,814,990, is 1.

Now, the common factors can be found like this.

685:5x 137

264:2x 2x 2x 3x 11

394:2x 197

814:2x 11x 37

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 3x 5x 11x 11 = 14520

Therefore, the value for common factors is 14520.

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 = 57418298625600/(1x14520)

LCM = 57418298625600/14520

LCM = 3954428280

Thus, we can understand that the LCM of 685,264,394,814,990 is 3954428280.
