Given numbers are 810,646,340,497

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

The LCM of 810,646,340,497 is 260060220.

Find LCM of 810,646,340,497 with Prime Factorization

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

2 x 5 x 17 x 81 x 19 x 2 x 497 = 260060220

Therefore, the lowest common multiple of 810,646,340,497 is 260060220.

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.

810 x 646 x 340 x 497 = 88420474800

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

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

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,646,340,497, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

646:2x 17x 19

340:2x 2x 5x 17

497:7x 71

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

2x 2x 5x 17 = 340

Therefore, the value for common factors is 340.

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 = 88420474800/(1x340)

LCM = 88420474800/340

LCM = 260060220

Thus, we can understand that the LCM of 810,646,340,497 is 260060220.
