Given numbers are 213,205,717,781

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

The LCM of 213,205,717,781 is 114795285.

Find LCM of 213,205,717,781 with Prime Factorization

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

3 x 71 x 1 x 205 x 239 x 11 = 114795285

Therefore, the lowest common multiple of 213,205,717,781 is 114795285.

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.

213 x 205 x 717 x 781 = 24451395705

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.

213 : 1, 3, 71, 213

205 : 1, 5, 41, 205

717 : 1, 3, 239, 717

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,205,717,781, is 1.

Now, the common factors can be found like this.

213:3x 71

205:5x 41

717:3x 239

781:11x 71

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

3x 71 = 213

Therefore, the value for common factors is 213.

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 = 24451395705/(1x213)

LCM = 24451395705/213

LCM = 114795285

Thus, we can understand that the LCM of 213,205,717,781 is 114795285.
