Calculate the LCM of 123,873,331,729

Given numbers are 123,873,331,729

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

The LCM of 123,873,331,729 is 959646123.

Find LCM of 123,873,331,729 with Prime Factorization


3 123, 873, 331, 729
3 41, 291, 331, 243
41, 97, 331, 81

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

3 x 3 x 41 x 97 x 331 x 81 = 959646123

Therefore, the lowest common multiple of 123,873,331,729 is 959646123.

LCM Formula to Find Lowest Common Multiple of 123,873,331,729

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 873 x 331 x 729 = 25910445321

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

873 : 1, 3, 9, 97, 291, 873

331 : 1, 331

729 : 1, 3, 9, 27, 81, 243, 729

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,873,331,729, is 1.

Now, the common factors can be found like this.

123:3x 41

873:3x 3x 97

331:331

729:3x 3x 3x 3x 3x 3

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 = 25910445321/(1x27)

LCM = 25910445321/27

LCM = 959646123

Thus, we can understand that the LCM of 123,873,331,729 is 959646123.
