Given numbers are 409,409,165,261,287

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

The LCM of 409,409,165,261,287 is 1685032965.

Find LCM of 409,409,165,261,287 with Prime Factorization

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

3 x 409 x 1 x 1 x 55 x 87 x 287 = 1685032965

Therefore, the lowest common multiple of 409,409,165,261,287 is 1685032965.

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.

409 x 409 x 165 x 261 x 287 = 2067535448055

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.

409 : 1, 409

409 : 1, 409

165 : 1, 3, 5, 11, 15, 33, 55, 165

261 : 1, 3, 9, 29, 87, 261

287 : 1, 7, 41, 287

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,409,165,261,287, is 1.

Now, the common factors can be found like this.

409:409

409:409

165:3x 5x 11

261:3x 3x 29

287:7x 41

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

3x 409 = 1227

Therefore, the value for common factors is 1227.

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 = 2067535448055/(1x1227)

LCM = 2067535448055/1227

LCM = 1685032965

Thus, we can understand that the LCM of 409,409,165,261,287 is 1685032965.
