Calculate the LCM of 789,411,945,123,408

Given numbers are 789,411,945,123,408

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

The LCM of 789,411,945,123,408 is 189858868920.

Find LCM of 789,411,945,123,408 with Prime Factorization


3 789, 411, 945, 123, 408
263, 137, 315, 41, 136

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

3 x 263 x 137 x 315 x 41 x 136 = 189858868920

Therefore, the lowest common multiple of 789,411,945,123,408 is 189858868920.

LCM Formula to Find Lowest Common Multiple of 789,411,945,123,408

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.

789 x 411 x 945 x 123 x 408 = 15378568382520

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.

789 : 1, 3, 263, 789

411 : 1, 3, 137, 411

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

123 : 1, 3, 41, 123

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,411,945,123,408, is 3.

Now, the common factors can be found like this.

789:3x 263

411:3x 137

945:3x 3x 3x 5x 7

123:3x 41

408:2x 2x 2x 3x 17

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 3 = 27

Therefore, the value for common factors is 27.

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 = 15378568382520/(3x27)

LCM = 15378568382520/81

LCM = 189858868920

Thus, we can understand that the LCM of 789,411,945,123,408 is 189858868920.
