LCM Formula to Find Lowest Common Multiple of 638,786,786,820

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.

638 x 786 x 786 x 820 = 323206155360

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

786 : 1, 2, 3, 6, 131, 262, 393, 786

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,786,786,820, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

786:2x 3x 131

820:2x 2x 5x 41

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 131 = 1572

Therefore, the value for common factors is 1572.

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 = 323206155360/(2x1572)

LCM = 323206155360/3144

LCM = 102800940

Thus, we can understand that the LCM of 638,786,786,820 is 102800940.
