Given numbers are 856,520,806,810

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

The LCM of 856,520,806,810 is 139712040.

Find LCM of 856,520,806,810 with Prime Factorization

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

2 x 2 x 2 x 5 x 13 x 107 x 1 x 31 x 81 = 139712040

Therefore, the lowest common multiple of 856,520,806,810 is 139712040.

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.

856 x 520 x 806 x 810 = 290601043200

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.

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

806 : 1, 2, 13, 26, 31, 62, 403, 806

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,520,806,810, is 2.

Now, the common factors can be found like this.

856:2x 2x 2x 107

520:2x 2x 2x 5x 13

806:2x 13x 31

810:2x 3x 3x 3x 3x 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 2x 2x 2x 5x 13 = 1040

Therefore, the value for common factors is 1040.

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 = 290601043200/(2x1040)

LCM = 290601043200/2080

LCM = 139712040

Thus, we can understand that the LCM of 856,520,806,810 is 139712040.
