Given numbers are 221,793,485,390

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

The LCM of 221,793,485,390 is 39229710.

Find LCM of 221,793,485,390 with Prime Factorization

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

5 x 13 x 17 x 61 x 97 x 6 = 39229710

Therefore, the lowest common multiple of 221,793,485,390 is 39229710.

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.

221 x 793 x 485 x 390 = 33149104950

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.

221 : 1, 13, 17, 221

793 : 1, 13, 61, 793

485 : 1, 5, 97, 485

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,793,485,390, is 1.

Now, the common factors can be found like this.

221:13x 17

793:13x 61

485:5x 97

390:2x 3x 5x 13

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

5x 13x 13 = 845

Therefore, the value for common factors is 845.

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 = 33149104950/(1x845)

LCM = 33149104950/845

LCM = 39229710

Thus, we can understand that the LCM of 221,793,485,390 is 39229710.
