Calculate the LCM of 243,681,689,856

Given numbers are 243,681,689,856

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

The LCM of 243,681,689,856 is 32533075224.

Find LCM of 243,681,689,856 with Prime Factorization


3 243, 681, 689, 856
81, 227, 689, 856

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

3 x 81 x 227 x 689 x 856 = 32533075224

Therefore, the lowest common multiple of 243,681,689,856 is 32533075224.

LCM Formula to Find Lowest Common Multiple of 243,681,689,856

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.

243 x 681 x 689 x 856 = 97599225672

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.

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

681 : 1, 3, 227, 681

689 : 1, 13, 53, 689

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,681,689,856, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

681:3x 227

689:13x 53

856:2x 2x 2x 107

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

3 = 3

Therefore, the value for common factors is 3.

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 = 97599225672/(1x3)

LCM = 97599225672/3

LCM = 32533075224

Thus, we can understand that the LCM of 243,681,689,856 is 32533075224.
