LCM Formula to Find Lowest Common Multiple of 779,195,390,845,720

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.

779 x 195 x 390 x 845 x 720 = 36043410780000

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.

779 : 1, 19, 41, 779

195 : 1, 3, 5, 13, 15, 39, 65, 195

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

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

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,195,390,845,720, is 1.

Now, the common factors can be found like this.

779:19x 41

195:3x 5x 13

390:2x 3x 5x 13

845:5x 13x 13

720:2x 2x 2x 2x 3x 3x 5

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 5x 5x 5x 13x 13 = 380250

Therefore, the value for common factors is 380250.

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 = 36043410780000/(1x380250)

LCM = 36043410780000/380250

LCM = 94788720

Thus, we can understand that the LCM of 779,195,390,845,720 is 94788720.
