Calculate the LCM of 861,721,953,933

Given numbers are 861,721,953,933

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

The LCM of 861,721,953,933 is 26284133589.

Find LCM of 861,721,953,933 with Prime Factorization


3 861, 721, 953, 933
7 287, 721, 953, 311
41, 103, 953, 311

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

3 x 7 x 41 x 103 x 953 x 311 = 26284133589

Therefore, the lowest common multiple of 861,721,953,933 is 26284133589.

LCM Formula to Find Lowest Common Multiple of 861,721,953,933

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.

861 x 721 x 953 x 933 = 551966805369

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

721 : 1, 7, 103, 721

953 : 1, 953

933 : 1, 3, 311, 933

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,721,953,933, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

721:7x 103

953:953

933:3x 311

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 551966805369/(1x21)

LCM = 551966805369/21

LCM = 26284133589

Thus, we can understand that the LCM of 861,721,953,933 is 26284133589.
