Given numbers are 209,165,879,640,421

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

The LCM of 209,165,879,640,421 is 49499091840.

Find LCM of 209,165,879,640,421 with Prime Factorization

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

3 x 5 x 11 x 19 x 1 x 293 x 128 x 421 = 49499091840

Therefore, the lowest common multiple of 209,165,879,640,421 is 49499091840.

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 165 x 879 x 640 x 421 = 8167350153600

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

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

879 : 1, 3, 293, 879

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,165,879,640,421, is 1.

Now, the common factors can be found like this.

209:11x 19

165:3x 5x 11

879:3x 293

640:2x 2x 2x 2x 2x 2x 2x 5

421:421

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

3x 5x 11 = 165

Therefore, the value for common factors is 165.

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 = 8167350153600/(1x165)

LCM = 8167350153600/165

LCM = 49499091840

Thus, we can understand that the LCM of 209,165,879,640,421 is 49499091840.
