Calculate the LCM of 827,707,867,128,405

Given numbers are 827,707,867,128,405

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

The LCM of 827,707,867,128,405 is 8759670272640.

Find LCM of 827,707,867,128,405 with Prime Factorization


3 827, 707, 867, 128, 405
827, 707, 289, 128, 135

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

3 x 827 x 707 x 289 x 128 x 135 = 8759670272640

Therefore, the lowest common multiple of 827,707,867,128,405 is 8759670272640.

LCM Formula to Find Lowest Common Multiple of 827,707,867,128,405

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.

827 x 707 x 867 x 128 x 405 = 26279010817920

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.

827 : 1, 827

707 : 1, 7, 101, 707

867 : 1, 3, 17, 51, 289, 867

128 : 1, 2, 4, 8, 16, 32, 64, 128

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 827,707,867,128,405, is 1.

Now, the common factors can be found like this.

827:827

707:7x 101

867:3x 17x 17

128:2x 2x 2x 2x 2x 2x 2

405:3x 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.

3 = 3

Therefore, the value for common factors is 3.

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 = 26279010817920/(1x3)

LCM = 26279010817920/3

LCM = 8759670272640

Thus, we can understand that the LCM of 827,707,867,128,405 is 8759670272640.
