Given numbers are 198,605,379,770,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,605,379,770,961 is 27764414370.
Find LCM of 198,605,379,770,961 with Prime Factorization
| 2 | 198, 605, 379, 770, 961 |
| 5 | 99, 605, 379, 385, 961 |
| 11 | 99, 121, 379, 77, 961 |
| 9, 11, 379, 7, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 9 x 11 x 379 x 7 x 961 = 27764414370
Therefore, the lowest common multiple of 198,605,379,770,961 is 27764414370.
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 605 x 379 x 770 x 961 = 33594941387700
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
605 : 1, 5, 11, 55, 121, 605
379 : 1, 379
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,605,379,770,961, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
605:5x 11x 11
379:379
770:2x 5x 7x 11
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 33594941387700/(1x1210)
LCM = 33594941387700/1210
LCM = 27764414370
Thus, we can understand that the LCM of 198,605,379,770,961 is 27764414370.
