Given numbers are 803,286,872,209

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

The LCM of 803,286,872,209 is 172953352.

Find LCM of 803,286,872,209 with Prime Factorization

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

2 x 11 x 73 x 13 x 436 x 19 = 172953352

Therefore, the lowest common multiple of 803,286,872,209 is 172953352.

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.

803 x 286 x 872 x 209 = 41854711184

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.

803 : 1, 11, 73, 803

286 : 1, 2, 11, 13, 22, 26, 143, 286

872 : 1, 2, 4, 8, 109, 218, 436, 872

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,286,872,209, is 1.

Now, the common factors can be found like this.

803:11x 73

286:2x 11x 13

872:2x 2x 2x 109

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.

2x 11x 11 = 242

Therefore, the value for common factors is 242.

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 = 41854711184/(1x242)

LCM = 41854711184/242

LCM = 172953352

Thus, we can understand that the LCM of 803,286,872,209 is 172953352.
