Given numbers are 810,214,856,69

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

The LCM of 810,214,856,69 is 7973640.

Find LCM of 810,214,856,69 with Prime Factorization

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

2 x 3 x 107 x 135 x 1 x 4 x 23 = 7973640

Therefore, the lowest common multiple of 810,214,856,69 is 7973640.

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 214 x 856 x 69 = 10238153760

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

214 : 1, 2, 107, 214

856 : 1, 2, 4, 8, 107, 214, 428, 856

69 : 1, 3, 23, 69

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,214,856,69, is 1.

Now, the common factors can be found like this.

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

214:2x 107

856:2x 2x 2x 107

69:3x 23

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 3x 107 = 1284

Therefore, the value for common factors is 1284.

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 = 10238153760/(1x1284)

LCM = 10238153760/1284

LCM = 7973640

Thus, we can understand that the LCM of 810,214,856,69 is 7973640.
