Given numbers are 561,209,286,913

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

The LCM of 561,209,286,913 is 23002122.

Find LCM of 561,209,286,913 with Prime Factorization

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

11 x 51 x 19 x 26 x 83 = 23002122

Therefore, the lowest common multiple of 561,209,286,913 is 23002122.

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.

561 x 209 x 286 x 913 = 30615824382

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

209 : 1, 11, 19, 209

286 : 1, 2, 11, 13, 22, 26, 143, 286

913 : 1, 11, 83, 913

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,209,286,913, is 11.

Now, the common factors can be found like this.

561:3x 11x 17

209:11x 19

286:2x 11x 13

913:11x 83

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 30615824382/(11x121)

LCM = 30615824382/1331

LCM = 23002122

Thus, we can understand that the LCM of 561,209,286,913 is 23002122.
