Calculate the LCM of 729,455,885,646,975

Given numbers are 729,455,885,646,975

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

The LCM of 729,455,885,646,975 is 63211116150.

Find LCM of 729,455,885,646,975 with Prime Factorization


3 729, 455, 885, 646, 975
5 243, 455, 295, 646, 325
13 243, 91, 59, 646, 65
243, 7, 59, 646, 5

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

3 x 5 x 13 x 243 x 7 x 59 x 646 x 5 = 63211116150

Therefore, the lowest common multiple of 729,455,885,646,975 is 63211116150.

LCM Formula to Find Lowest Common Multiple of 729,455,885,646,975

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 455 x 885 x 646 x 975 = 184892514738750

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

885 : 1, 3, 5, 15, 59, 177, 295, 885

646 : 1, 2, 17, 19, 34, 38, 323, 646

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,455,885,646,975, is 1.

Now, the common factors can be found like this.

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

455:5x 7x 13

885:3x 5x 59

646:2x 17x 19

975:3x 5x 5x 13

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 5x 5x 13 = 2925

Therefore, the value for common factors is 2925.

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 = 184892514738750/(1x2925)

LCM = 184892514738750/2925

LCM = 63211116150

Thus, we can understand that the LCM of 729,455,885,646,975 is 63211116150.
