Given numbers are 256,193,354,128

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

The LCM of 256,193,354,128 is 8745216.

Find LCM of 256,193,354,128 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 1 x 193 x 177 x 2 = 8745216

Therefore, the lowest common multiple of 256,193,354,128 is 8745216.

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 193 x 354 x 128 = 2238775296

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

193 : 1, 193

354 : 1, 2, 3, 6, 59, 118, 177, 354

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,193,354,128, is 1.

Now, the common factors can be found like this.

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

193:193

354:2x 3x 59

128:2x 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 2x 2x 2 = 256

Therefore, the value for common factors is 256.

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 = 2238775296/(1x256)

LCM = 2238775296/256

LCM = 8745216

Thus, we can understand that the LCM of 256,193,354,128 is 8745216.
