Calculate the LCM of 165,665,921,181

Given numbers are 165,665,921,181

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

The LCM of 165,665,921,181 is 1219417815.

Find LCM of 165,665,921,181 with Prime Factorization


3 165, 665, 921, 181
5 55, 665, 307, 181
11, 133, 307, 181

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

3 x 5 x 11 x 133 x 307 x 181 = 1219417815

Therefore, the lowest common multiple of 165,665,921,181 is 1219417815.

LCM Formula to Find Lowest Common Multiple of 165,665,921,181

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.

165 x 665 x 921 x 181 = 18291267225

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.

165 : 1, 3, 5, 11, 15, 33, 55, 165

665 : 1, 5, 7, 19, 35, 95, 133, 665

921 : 1, 3, 307, 921

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,665,921,181, is 1.

Now, the common factors can be found like this.

165:3x 5x 11

665:5x 7x 19

921:3x 307

181:181

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 18291267225/(1x15)

LCM = 18291267225/15

LCM = 1219417815

Thus, we can understand that the LCM of 165,665,921,181 is 1219417815.
