The LCM of 297,180,217,405 is 3866940.

Find LCM of 297,180,217,405 with Prime Factorization


3 297, 180, 217, 405
3 99, 60, 217, 135
3 33, 20, 217, 45
5 11, 20, 217, 15
11, 4, 217, 3

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

3 x 3 x 3 x 5 x 11 x 4 x 217 x 3 = 3866940

Therefore, the lowest common multiple of 297,180,217,405 is 3866940.

LCM Formula to Find Lowest Common Multiple of 297,180,217,405

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.

297 x 180 x 217 x 405 = 4698332100

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

217 : 1, 7, 31, 217

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 297,180,217,405, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

180:2x 2x 3x 3x 5

217:7x 31

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 = 4698332100/(1x1215)

LCM = 4698332100/1215

LCM = 3866940

Thus, we can understand that the LCM of 297,180,217,405 is 3866940.
