Given numbers are 666,866,161,422,257

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

The LCM of 666,866,161,422,257 is 2517697682766.

Find LCM of 666,866,161,422,257 with Prime Factorization

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

2 x 333 x 433 x 161 x 211 x 257 = 2517697682766

Therefore, the lowest common multiple of 666,866,161,422,257 is 2517697682766.

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.

666 x 866 x 161 x 422 x 257 = 10070790731064

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.

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

866 : 1, 2, 433, 866

161 : 1, 7, 23, 161

422 : 1, 2, 211, 422

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,866,161,422,257, is 1.

Now, the common factors can be found like this.

666:2x 3x 3x 37

866:2x 433

161:7x 23

422:2x 211

257:257

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 10070790731064/(1x4)

LCM = 10070790731064/4

LCM = 2517697682766

Thus, we can understand that the LCM of 666,866,161,422,257 is 2517697682766.
