Given numbers are 405,728,195,403,479

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

The LCM of 405,728,195,403,479 is 4378079160.

Find LCM of 405,728,195,403,479 with Prime Factorization

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

3 x 5 x 13 x 27 x 56 x 1 x 31 x 479 = 4378079160

Therefore, the lowest common multiple of 405,728,195,403,479 is 4378079160.

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.

405 x 728 x 195 x 403 x 479 = 11098430670600

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.

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

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

195 : 1, 3, 5, 13, 15, 39, 65, 195

403 : 1, 13, 31, 403

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,728,195,403,479, is 1.

Now, the common factors can be found like this.

405:3x 3x 3x 3x 5

728:2x 2x 2x 7x 13

195:3x 5x 13

403:13x 31

479:479

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

3x 5x 13x 13 = 2535

Therefore, the value for common factors is 2535.

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 = 11098430670600/(1x2535)

LCM = 11098430670600/2535

LCM = 4378079160

Thus, we can understand that the LCM of 405,728,195,403,479 is 4378079160.
