Given numbers are 209,989,781,396,209

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

The LCM of 209,989,781,396,209 is 528327756.

Find LCM of 209,989,781,396,209 with Prime Factorization

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

11 x 19 x 1 x 989 x 71 x 36 x 1 = 528327756

Therefore, the lowest common multiple of 209,989,781,396,209 is 528327756.

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 989 x 781 x 396 x 209 = 13360880621484

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

989 : 1, 23, 43, 989

781 : 1, 11, 71, 781

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,989,781,396,209, is 1.

Now, the common factors can be found like this.

209:11x 19

989:23x 43

781:11x 71

396:2x 2x 3x 3x 11

209:11x 19

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 11x 19 = 25289

Therefore, the value for common factors is 25289.

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 = 13360880621484/(1x25289)

LCM = 13360880621484/25289

LCM = 528327756

Thus, we can understand that the LCM of 209,989,781,396,209 is 528327756.
