LCM Formula to Find Lowest Common Multiple of 765,108,782,306,814

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.

765 x 108 x 782 x 306 x 814 = 16093028302560

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.

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

782 : 1, 2, 17, 23, 34, 46, 391, 782

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

814 : 1, 2, 11, 22, 37, 74, 407, 814

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,108,782,306,814, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

108:2x 2x 3x 3x 3

782:2x 17x 23

306:2x 3x 3x 17

814:2x 11x 37

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 3x 3x 3x 3x 17x 17 = 187272

Therefore, the value for common factors is 187272.

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 = 16093028302560/(1x187272)

LCM = 16093028302560/187272

LCM = 85933980

Thus, we can understand that the LCM of 765,108,782,306,814 is 85933980.
