LCM Formula to Find Lowest Common Multiple of 768,781,605,661

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.

768 x 781 x 605 x 661 = 239866218240

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.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

781 : 1, 11, 71, 781

605 : 1, 5, 11, 55, 121, 605

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,781,605,661, is 1.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

781:11x 71

605:5x 11x 11

661:661

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

11 = 11

Therefore, the value for common factors is 11.

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 = 239866218240/(1x11)

LCM = 239866218240/11

LCM = 21806019840

Thus, we can understand that the LCM of 768,781,605,661 is 21806019840.
