Calculate the LCM of 897,138,377,872

Given numbers are 897,138,377,872

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

The LCM of 897,138,377,872 is 22683336.

Find LCM of 897,138,377,872 with Prime Factorization


2 897, 138, 377, 872
3 897, 69, 377, 436
13 299, 23, 377, 436
23 23, 23, 29, 436
1, 1, 29, 436

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

2 x 3 x 13 x 23 x 1 x 1 x 29 x 436 = 22683336

Therefore, the lowest common multiple of 897,138,377,872 is 22683336.

LCM Formula to Find Lowest Common Multiple of 897,138,377,872

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.

897 x 138 x 377 x 872 = 40693904784

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

138 : 1, 2, 3, 6, 23, 46, 69, 138

377 : 1, 13, 29, 377

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,138,377,872, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

138:2x 3x 23

377:13x 29

872:2x 2x 2x 109

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

2x 3x 13x 23 = 1794

Therefore, the value for common factors is 1794.

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 = 40693904784/(1x1794)

LCM = 40693904784/1794

LCM = 22683336

Thus, we can understand that the LCM of 897,138,377,872 is 22683336.
