LCM Formula to Find Lowest Common Multiple of 840,812,413,388,725

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.

840 x 812 x 413 x 388 x 725 = 79241939952000

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

413 : 1, 7, 59, 413

388 : 1, 2, 4, 97, 194, 388

725 : 1, 5, 25, 29, 145, 725

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,812,413,388,725, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

812:2x 2x 7x 29

413:7x 59

388:2x 2x 97

725:5x 5x 29

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 5x 7x 7x 29 = 113680

Therefore, the value for common factors is 113680.

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 = 79241939952000/(1x113680)

LCM = 79241939952000/113680

LCM = 697061400

Thus, we can understand that the LCM of 840,812,413,388,725 is 697061400.
