LCM Formula to Find Lowest Common Multiple of 615,642,736,990,897

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.

615 x 642 x 736 x 990 x 897 = 258056971286400

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

642 : 1, 2, 3, 6, 107, 214, 321, 642

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

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

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,642,736,990,897, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

642:2x 3x 107

736:2x 2x 2x 2x 2x 23

990:2x 3x 3x 5x 11

897:3x 13x 23

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 3x 3x 3x 5x 23 = 12420

Therefore, the value for common factors is 12420.

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 = 258056971286400/(1x12420)

LCM = 258056971286400/12420

LCM = 20777533920

Thus, we can understand that the LCM of 615,642,736,990,897 is 20777533920.
