Given numbers are 810,744,865,309

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

The LCM of 810,744,865,309 is 1789740360.

Find LCM of 810,744,865,309 with Prime Factorization

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

2 x 3 x 5 x 27 x 124 x 173 x 103 = 1789740360

Therefore, the lowest common multiple of 810,744,865,309 is 1789740360.

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 744 x 865 x 309 = 161076632400

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

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

865 : 1, 5, 173, 865

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,744,865,309, is 1.

Now, the common factors can be found like this.

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

744:2x 2x 2x 3x 31

865:5x 173

309:3x 103

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

2x 3x 3x 5 = 90

Therefore, the value for common factors is 90.

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 = 161076632400/(1x90)

LCM = 161076632400/90

LCM = 1789740360

Thus, we can understand that the LCM of 810,744,865,309 is 1789740360.
