Calculate the LCM of 243,664,209,847

Given numbers are 243,664,209,847

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

The LCM of 243,664,209,847 is 2596637736.

Find LCM of 243,664,209,847 with Prime Factorization


11 243, 664, 209, 847
243, 664, 19, 77

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

11 x 243 x 664 x 19 x 77 = 2596637736

Therefore, the lowest common multiple of 243,664,209,847 is 2596637736.

LCM Formula to Find Lowest Common Multiple of 243,664,209,847

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 664 x 209 x 847 = 28563015096

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

209 : 1, 11, 19, 209

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,664,209,847, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

664:2x 2x 2x 83

209:11x 19

847:7x 11x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 28563015096/(1x11)

LCM = 28563015096/11

LCM = 2596637736

Thus, we can understand that the LCM of 243,664,209,847 is 2596637736.
