The LCM of 981,990,705,605,334 is 9316841490.
Find LCM of 981,990,705,605,334 with Prime Factorization
| 2 | 981, 990, 705, 605, 334 |
| 3 | 981, 495, 705, 605, 167 |
| 3 | 327, 165, 235, 605, 167 |
| 5 | 109, 55, 235, 605, 167 |
| 11 | 109, 11, 47, 121, 167 |
| 109, 1, 47, 11, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 109 x 1 x 47 x 11 x 167 = 9316841490
Therefore, the lowest common multiple of 981,990,705,605,334 is 9316841490.
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.
981 x 990 x 705 x 605 x 334 = 138355096126500
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.
981 : 1, 3, 9, 109, 327, 981
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
705 : 1, 3, 5, 15, 47, 141, 235, 705
605 : 1, 5, 11, 55, 121, 605
334 : 1, 2, 167, 334
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,990,705,605,334, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
990:2x 3x 3x 5x 11
705:3x 5x 47
605:5x 11x 11
334:2x 167
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 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 138355096126500/(1x14850)
LCM = 138355096126500/14850
LCM = 9316841490
Thus, we can understand that the LCM of 981,990,705,605,334 is 9316841490.
