Given numbers are 209,436,209,435

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

The LCM of 209,436,209,435 is 39638940.

Find LCM of 209,436,209,435 with Prime Factorization

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

11 x 19 x 1 x 436 x 1 x 435 = 39638940

Therefore, the lowest common multiple of 209,436,209,435 is 39638940.

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 436 x 209 x 435 = 8284538460

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

436 : 1, 2, 4, 109, 218, 436

209 : 1, 11, 19, 209

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,436,209,435, is 1.

Now, the common factors can be found like this.

209:11x 19

436:2x 2x 109

209:11x 19

435:3x 5x 29

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 = 8284538460/(1x209)

LCM = 8284538460/209

LCM = 39638940

Thus, we can understand that the LCM of 209,436,209,435 is 39638940.
