Find LCM of 198,879,905,774,543 with Prime Factorization
| 2 | 198, 879, 905, 774, 543 |
| 3 | 99, 879, 905, 387, 543 |
| 3 | 33, 293, 905, 129, 181 |
| 181 | 11, 293, 905, 43, 181 |
| 11, 293, 5, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 181 x 11 x 293 x 5 x 43 x 1 = 2257614810
Therefore, the lowest common multiple of 198,879,905,774,543 is 2257614810.
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 879 x 905 x 774 x 543 = 66197781458820
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
879 : 1, 3, 293, 879
905 : 1, 5, 181, 905
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
543 : 1, 3, 181, 543
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,879,905,774,543, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
879:3x 293
905:5x 181
774:2x 3x 3x 43
543:3x 181
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 3x 181 = 29322
Therefore, the value for common factors is 29322.
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 = 66197781458820/(1x29322)
LCM = 66197781458820/29322
LCM = 2257614810
Thus, we can understand that the LCM of 198,879,905,774,543 is 2257614810.
