Find LCM of 243,171,940,729 with Prime Factorization


3 243, 171, 940, 729
3 81, 57, 940, 243
3 27, 19, 940, 81
3 9, 19, 940, 27
3 3, 19, 940, 9
1, 19, 940, 3

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

3 x 3 x 3 x 3 x 3 x 1 x 19 x 940 x 3 = 13019940

Therefore, the lowest common multiple of 243,171,940,729 is 13019940.

LCM Formula to Find Lowest Common Multiple of 243,171,940,729

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.

243 x 171 x 940 x 729 = 28474608780

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

171 : 1, 3, 9, 19, 57, 171

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

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 243,171,940,729, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

171:3x 3x 19

940:2x 2x 5x 47

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 3x 3x 3x 3x 3 = 2187

Therefore, the value for common factors is 2187.

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 = 28474608780/(1x2187)

LCM = 28474608780/2187

LCM = 13019940

Thus, we can understand that the LCM of 243,171,940,729 is 13019940.
