The LCM of 912,826,891,638 is 3244138128.

Find LCM of 912,826,891,638 with Prime Factorization


2 912, 826, 891, 638
3 456, 413, 891, 319
11 152, 413, 297, 319
152, 413, 27, 29

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

2 x 3 x 11 x 152 x 413 x 27 x 29 = 3244138128

Therefore, the lowest common multiple of 912,826,891,638 is 3244138128.

LCM Formula to Find Lowest Common Multiple of 912,826,891,638

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.

912 x 826 x 891 x 638 = 428226232896

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.

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

826 : 1, 2, 7, 14, 59, 118, 413, 826

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,826,891,638, is 1.

Now, the common factors can be found like this.

912:2x 2x 2x 2x 3x 19

826:2x 7x 59

891:3x 3x 3x 3x 11

638:2x 11x 29

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

2x 2x 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 428226232896/(1x132)

LCM = 428226232896/132

LCM = 3244138128

Thus, we can understand that the LCM of 912,826,891,638 is 3244138128.
