Given numbers are 355,128,473,903

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

The LCM of 355,128,473,903 is 451355520.

Find LCM of 355,128,473,903 with Prime Factorization

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

43 x 355 x 128 x 11 x 21 = 451355520

Therefore, the lowest common multiple of 355,128,473,903 is 451355520.

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 128 x 473 x 903 = 19408287360

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

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

473 : 1, 11, 43, 473

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,128,473,903, is 1.

Now, the common factors can be found like this.

355:5x 71

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

473:11x 43

903:3x 7x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

43 = 43

Therefore, the value for common factors is 43.

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 = 19408287360/(1x43)

LCM = 19408287360/43

LCM = 451355520

Thus, we can understand that the LCM of 355,128,473,903 is 451355520.
