LCM Formula to Find Lowest Common Multiple of 399,396,297,429,728

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.

399 x 396 x 297 x 429 x 728 = 14655923938656

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,396,297,429,728, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

396:2x 2x 3x 3x 11

297:3x 3x 3x 11

429:3x 11x 13

728:2x 2x 2x 7x 13

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 3x 3x 3x 7x 11x 11x 13 = 3567564

Therefore, the value for common factors is 3567564.

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 = 14655923938656/(1x3567564)

LCM = 14655923938656/3567564

LCM = 4108104

Thus, we can understand that the LCM of 399,396,297,429,728 is 4108104.
