Given numbers are 355,481,128,722,128

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

The LCM of 355,481,128,722,128 is 7890247040.

Find LCM of 355,481,128,722,128 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 355 x 481 x 1 x 361 x 1 = 7890247040

Therefore, the lowest common multiple of 355,481,128,722,128 is 7890247040.

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.

355 x 481 x 128 x 722 x 128 = 2019903242240

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.

355 : 1, 5, 71, 355

481 : 1, 13, 37, 481

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

722 : 1, 2, 19, 38, 361, 722

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 355,481,128,722,128, is 1.

Now, the common factors can be found like this.

355:5x 71

481:13x 37

128:2x 2x 2x 2x 2x 2x 2

722:2x 19x 19

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 = 2019903242240/(1x256)

LCM = 2019903242240/256

LCM = 7890247040

Thus, we can understand that the LCM of 355,481,128,722,128 is 7890247040.
