The LCM of 198,561,918,753 is 2534598.
Find LCM of 198,561,918,753 with Prime Factorization
| 2 | 198, 561, 918, 753 |
| 3 | 99, 561, 459, 753 |
| 3 | 33, 187, 153, 251 |
| 11 | 11, 187, 51, 251 |
| 17 | 1, 17, 51, 251 |
| 1, 1, 3, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 17 x 1 x 1 x 3 x 251 = 2534598
Therefore, the lowest common multiple of 198,561,918,753 is 2534598.
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 561 x 918 x 753 = 76783111812
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
753 : 1, 3, 251, 753
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,561,918,753, is 3.
Now, the common factors can be found like this.
198:2x 3x 3x 11
561:3x 11x 17
918:2x 3x 3x 3x 17
753:3x 251
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 3x 3x 11x 17 = 10098
Therefore, the value for common factors is 10098.
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 = 76783111812/(3x10098)
LCM = 76783111812/30294
LCM = 2534598
Thus, we can understand that the LCM of 198,561,918,753 is 2534598.
