Given numbers are 102,289,811,221

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

The LCM of 102,289,811,221 is 18281562.

Find LCM of 102,289,811,221 with Prime Factorization

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

17 x 6 x 17 x 811 x 13 = 18281562

Therefore, the lowest common multiple of 102,289,811,221 is 18281562.

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.

102 x 289 x 811 x 221 = 5283371418

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

289 : 1, 17, 289

811 : 1, 811

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,289,811,221, is 1.

Now, the common factors can be found like this.

102:2x 3x 17

289:17x 17

811:811

221:13x 17

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 5283371418/(1x289)

LCM = 5283371418/289

LCM = 18281562

Thus, we can understand that the LCM of 102,289,811,221 is 18281562.
