Calculate the LCM of 163,243,840,405

Given numbers are 163,243,840,405

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

The LCM of 163,243,840,405 is 11090520.

Find LCM of 163,243,840,405 with Prime Factorization


3 163, 243, 840, 405
3 163, 81, 280, 135
3 163, 27, 280, 45
3 163, 9, 280, 15
5 163, 3, 280, 5
163, 3, 56, 1

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

3 x 3 x 3 x 3 x 5 x 163 x 3 x 56 x 1 = 11090520

Therefore, the lowest common multiple of 163,243,840,405 is 11090520.

LCM Formula to Find Lowest Common Multiple of 163,243,840,405

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.

163 x 243 x 840 x 405 = 13474981800

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.

163 : 1, 163

243 : 1, 3, 9, 27, 81, 243

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

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 163,243,840,405, is 1.

Now, the common factors can be found like this.

163:163

243:3x 3x 3x 3x 3

840:2x 2x 2x 3x 5x 7

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.

3x 3x 3x 3x 3x 5 = 1215

Therefore, the value for common factors is 1215.

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 = 13474981800/(1x1215)

LCM = 13474981800/1215

LCM = 11090520

Thus, we can understand that the LCM of 163,243,840,405 is 11090520.
