LCM Formula to Find Lowest Common Multiple of 891,345,816,437

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.

891 x 345 x 816 x 437 = 109614597840

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

345 : 1, 3, 5, 15, 23, 69, 115, 345

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,345,816,437, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

345:3x 5x 23

816:2x 2x 2x 2x 3x 17

437:19x 23

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

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 109614597840/(1x207)

LCM = 109614597840/207

LCM = 529539120

Thus, we can understand that the LCM of 891,345,816,437 is 529539120.
