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

3 x 3 x 5 x 13 x 18 x 1 x 13 x 421 = 57630690

Therefore, the lowest common multiple of 810,845,585,421 is 57630690.

LCM Formula to Find Lowest Common Multiple of 810,845,585,421

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.

810 x 845 x 585 x 421 = 168569768250

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

845 : 1, 5, 13, 65, 169, 845

585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,845,585,421, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

845:5x 13x 13

585:3x 3x 5x 13

421:421

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 5x 5x 13 = 2925

Therefore, the value for common factors is 2925.

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 = 168569768250/(1x2925)

LCM = 168569768250/2925

LCM = 57630690

Thus, we can understand that the LCM of 810,845,585,421 is 57630690.
