Given numbers are 209,957,845,121

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

The LCM of 209,957,845,121 is 169010985.

Find LCM of 209,957,845,121 with Prime Factorization

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

11 x 19 x 87 x 845 x 11 = 169010985

Therefore, the lowest common multiple of 209,957,845,121 is 169010985.

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.

209 x 957 x 845 x 121 = 20450329185

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.

209 : 1, 11, 19, 209

957 : 1, 3, 11, 29, 33, 87, 319, 957

845 : 1, 5, 13, 65, 169, 845

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,957,845,121, is 1.

Now, the common factors can be found like this.

209:11x 19

957:3x 11x 29

845:5x 13x 13

121:11x 11

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 = 20450329185/(1x121)

LCM = 20450329185/121

LCM = 169010985

Thus, we can understand that the LCM of 209,957,845,121 is 169010985.
