Given numbers are 685,264,857,845,805

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

The LCM of 685,264,857,845,805 is 4216847554920.

Find LCM of 685,264,857,845,805 with Prime Factorization

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

5 x 137 x 264 x 857 x 169 x 161 = 4216847554920

Therefore, the lowest common multiple of 685,264,857,845,805 is 4216847554920.

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.

685 x 264 x 857 x 845 x 805 = 105421188873000

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.

685 : 1, 5, 137, 685

264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264

857 : 1, 857

845 : 1, 5, 13, 65, 169, 845

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,264,857,845,805, is 1.

Now, the common factors can be found like this.

685:5x 137

264:2x 2x 2x 3x 11

857:857

845:5x 13x 13

805:5x 7x 23

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 105421188873000/(1x25)

LCM = 105421188873000/25

LCM = 4216847554920

Thus, we can understand that the LCM of 685,264,857,845,805 is 4216847554920.
