LCM Formula to Find Lowest Common Multiple of 710,191,992,864,781

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.

710 x 191 x 992 x 864 x 781 = 90775398574080

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.

710 : 1, 2, 5, 10, 71, 142, 355, 710

191 : 1, 191

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 710,191,992,864,781, is 1.

Now, the common factors can be found like this.

710:2x 5x 71

191:191

992:2x 2x 2x 2x 2x 31

864:2x 2x 2x 2x 2x 3x 3x 3

781:11x 71

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 2x 2x 2x 71 = 4544

Therefore, the value for common factors is 4544.

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 = 90775398574080/(1x4544)

LCM = 90775398574080/4544

LCM = 19976980320

Thus, we can understand that the LCM of 710,191,992,864,781 is 19976980320.
