Given numbers are 205,781,781,121

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

The LCM of 205,781,781,121 is 1761155.

Find LCM of 205,781,781,121 with Prime Factorization

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

11 x 71 x 205 x 1 x 1 x 11 = 1761155

Therefore, the lowest common multiple of 205,781,781,121 is 1761155.

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.

205 x 781 x 781 x 121 = 15130082605

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.

205 : 1, 5, 41, 205

781 : 1, 11, 71, 781

781 : 1, 11, 71, 781

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,781,781,121, is 1.

Now, the common factors can be found like this.

205:5x 41

781:11x 71

781:11x 71

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 11x 71 = 8591

Therefore, the value for common factors is 8591.

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 = 15130082605/(1x8591)

LCM = 15130082605/8591

LCM = 1761155

Thus, we can understand that the LCM of 205,781,781,121 is 1761155.
