Given numbers are 256,129,728,556,416

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 256,129,728,556,416 is 417720576.

Find LCM of 256,129,728,556,416 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 13 x 8 x 129 x 7 x 139 x 1 = 417720576

Therefore, the lowest common multiple of 256,129,728,556,416 is 417720576.

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.

256 x 129 x 728 x 556 x 416 = 5560696307712

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.

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

129 : 1, 3, 43, 129

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

556 : 1, 2, 4, 139, 278, 556

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,129,728,556,416, is 1.

Now, the common factors can be found like this.

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

129:3x 43

728:2x 2x 2x 7x 13

556:2x 2x 139

416:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 2x 2x 2x 13 = 13312

Therefore, the value for common factors is 13312.

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 = 5560696307712/(1x13312)

LCM = 5560696307712/13312

LCM = 417720576

Thus, we can understand that the LCM of 256,129,728,556,416 is 417720576.
