LCM Formula to Find Lowest Common Multiple of 813,693,990,412,657

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.

813 x 693 x 990 x 412 x 657 = 150980743738440

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.

813 : 1, 3, 271, 813

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

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

412 : 1, 2, 4, 103, 206, 412

657 : 1, 3, 9, 73, 219, 657

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,693,990,412,657, is 1.

Now, the common factors can be found like this.

813:3x 271

693:3x 3x 7x 11

990:2x 3x 3x 5x 11

412:2x 2x 103

657:3x 3x 73

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

2x 3x 3x 3x 3x 3x 11 = 5346

Therefore, the value for common factors is 5346.

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 = 150980743738440/(1x5346)

LCM = 150980743738440/5346

LCM = 28241815140

Thus, we can understand that the LCM of 813,693,990,412,657 is 28241815140.
