Given numbers are 221,872,261,568

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

The LCM of 221,872,261,568 is 3571146072.

Find LCM of 221,872,261,568 with Prime Factorization

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

2 x 2 x 2 x 221 x 109 x 261 x 71 = 3571146072

Therefore, the lowest common multiple of 221,872,261,568 is 3571146072.

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 872 x 261 x 568 = 28569168576

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

872 : 1, 2, 4, 8, 109, 218, 436, 872

261 : 1, 3, 9, 29, 87, 261

568 : 1, 2, 4, 8, 71, 142, 284, 568

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,872,261,568, is 1.

Now, the common factors can be found like this.

221:13x 17

872:2x 2x 2x 109

261:3x 3x 29

568:2x 2x 2x 71

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 2 = 8

Therefore, the value for common factors is 8.

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 = 28569168576/(1x8)

LCM = 28569168576/8

LCM = 3571146072

Thus, we can understand that the LCM of 221,872,261,568 is 3571146072.
