Calculate the LCM of 123,813,608,561

Given numbers are 123,813,608,561

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

The LCM of 123,813,608,561 is 3789828768.

Find LCM of 123,813,608,561 with Prime Factorization


3 123, 813, 608, 561
41, 271, 608, 187

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

3 x 41 x 271 x 608 x 187 = 3789828768

Therefore, the lowest common multiple of 123,813,608,561 is 3789828768.

LCM Formula to Find Lowest Common Multiple of 123,813,608,561

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.

123 x 813 x 608 x 561 = 34108458912

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.

123 : 1, 3, 41, 123

813 : 1, 3, 271, 813

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,813,608,561, is 1.

Now, the common factors can be found like this.

123:3x 41

813:3x 271

608:2x 2x 2x 2x 2x 19

561:3x 11x 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 3 = 9

Therefore, the value for common factors is 9.

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 = 34108458912/(1x9)

LCM = 34108458912/9

LCM = 3789828768

Thus, we can understand that the LCM of 123,813,608,561 is 3789828768.
