Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 2 x 3 x 13 x 9 x 11 x 41 x 16 = 40525056

Therefore, the lowest common multiple of 351,858,656,256 is 40525056.

LCM Formula to Find Lowest Common Multiple of 351,858,656,256

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.

351 x 858 x 656 x 256 = 50575269888

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,858,656,256, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

858:2x 3x 11x 13

656:2x 2x 2x 2x 41

256:2x 2x 2x 2x 2x 2x 2x 2

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 2x 3x 13 = 1248

Therefore, the value for common factors is 1248.

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 = 50575269888/(1x1248)

LCM = 50575269888/1248

LCM = 40525056

Thus, we can understand that the LCM of 351,858,656,256 is 40525056.
