Calculate the LCM of 834,561,398,638

Given numbers are 834,561,398,638

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

The LCM of 834,561,398,638 is 900033618.

Find LCM of 834,561,398,638 with Prime Factorization


2 834, 561, 398, 638
3 417, 561, 199, 319
11 139, 187, 199, 319
139, 17, 199, 29

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

2 x 3 x 11 x 139 x 17 x 199 x 29 = 900033618

Therefore, the lowest common multiple of 834,561,398,638 is 900033618.

LCM Formula to Find Lowest Common Multiple of 834,561,398,638

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.

834 x 561 x 398 x 638 = 118804437576

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.

834 : 1, 2, 3, 6, 139, 278, 417, 834

561 : 1, 3, 11, 17, 33, 51, 187, 561

398 : 1, 2, 199, 398

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 834,561,398,638, is 1.

Now, the common factors can be found like this.

834:2x 3x 139

561:3x 11x 17

398:2x 199

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 = 118804437576/(1x132)

LCM = 118804437576/132

LCM = 900033618

Thus, we can understand that the LCM of 834,561,398,638 is 900033618.
