Given numbers are 209,380,781,271

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

The LCM of 209,380,781,271 is 80427380.

Find LCM of 209,380,781,271 with Prime Factorization

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

11 x 19 x 1 x 20 x 71 x 271 = 80427380

Therefore, the lowest common multiple of 209,380,781,271 is 80427380.

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 380 x 781 x 271 = 16809322420

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

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

781 : 1, 11, 71, 781

271 : 1, 271

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,380,781,271, is 1.

Now, the common factors can be found like this.

209:11x 19

380:2x 2x 5x 19

781:11x 71

271:271

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 16809322420/(1x209)

LCM = 16809322420/209

LCM = 80427380

Thus, we can understand that the LCM of 209,380,781,271 is 80427380.
