Find LCM of 198,638,916,729 with Prime Factorization


2 198, 638, 916, 729
3 99, 319, 458, 729
3 33, 319, 458, 243
11 11, 319, 458, 81
1, 29, 458, 81

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

2 x 3 x 3 x 11 x 1 x 29 x 458 x 81 = 213016716

Therefore, the lowest common multiple of 198,638,916,729 is 213016716.

LCM Formula to Find Lowest Common Multiple of 198,638,916,729

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.

198 x 638 x 916 x 729 = 84354619536

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

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

916 : 1, 2, 4, 229, 458, 916

729 : 1, 3, 9, 27, 81, 243, 729

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,638,916,729, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

638:2x 11x 29

916:2x 2x 229

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

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 3x 11 = 396

Therefore, the value for common factors is 396.

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 = 84354619536/(1x396)

LCM = 84354619536/396

LCM = 213016716

Thus, we can understand that the LCM of 198,638,916,729 is 213016716.
