Calculate the LCM of 729,355,675,691

Given numbers are 729,355,675,691

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

The LCM of 729,355,675,691 is 894136725.

Find LCM of 729,355,675,691 with Prime Factorization


3 729, 355, 675, 691
3 243, 355, 225, 691
3 81, 355, 75, 691
5 27, 355, 25, 691
27, 71, 5, 691

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

3 x 3 x 3 x 5 x 27 x 71 x 5 x 691 = 894136725

Therefore, the lowest common multiple of 729,355,675,691 is 894136725.

LCM Formula to Find Lowest Common Multiple of 729,355,675,691

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.

729 x 355 x 675 x 691 = 120708457875

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.

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

355 : 1, 5, 71, 355

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,355,675,691, is 1.

Now, the common factors can be found like this.

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

355:5x 71

675:3x 3x 3x 5x 5

691:691

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 5 = 135

Therefore, the value for common factors is 135.

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 = 120708457875/(1x135)

LCM = 120708457875/135

LCM = 894136725

Thus, we can understand that the LCM of 729,355,675,691 is 894136725.
