Given numbers are 646,273,539,800

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

The LCM of 646,273,539,800 is 5431826400.

Find LCM of 646,273,539,800 with Prime Factorization

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

2 x 7 x 323 x 39 x 77 x 400 = 5431826400

Therefore, the lowest common multiple of 646,273,539,800 is 5431826400.

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.

646 x 273 x 539 x 800 = 76045569600

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

273 : 1, 3, 7, 13, 21, 39, 91, 273

539 : 1, 7, 11, 49, 77, 539

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,273,539,800, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

273:3x 7x 13

539:7x 7x 11

800:2x 2x 2x 2x 2x 5x 5

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 76045569600/(1x14)

LCM = 76045569600/14

LCM = 5431826400

Thus, we can understand that the LCM of 646,273,539,800 is 5431826400.
