Given numbers are 221,638,363,541

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

The LCM of 221,638,363,541 is 2517237294.

Find LCM of 221,638,363,541 with Prime Factorization

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

11 x 221 x 58 x 33 x 541 = 2517237294

Therefore, the lowest common multiple of 221,638,363,541 is 2517237294.

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 638 x 363 x 541 = 27689610234

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

363 : 1, 3, 11, 33, 121, 363

541 : 1, 541

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,638,363,541, is 1.

Now, the common factors can be found like this.

221:13x 17

638:2x 11x 29

363:3x 11x 11

541:541

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

11 = 11

Therefore, the value for common factors is 11.

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 = 27689610234/(1x11)

LCM = 27689610234/11

LCM = 2517237294

Thus, we can understand that the LCM of 221,638,363,541 is 2517237294.
