The LCM of 454,990,891,790 is 159783030.
Find LCM of 454,990,891,790 with Prime Factorization
| 2 | 454, 990, 891, 790 |
| 3 | 227, 495, 891, 395 |
| 3 | 227, 165, 297, 395 |
| 5 | 227, 55, 99, 395 |
| 11 | 227, 11, 99, 79 |
| 227, 1, 9, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 227 x 1 x 9 x 79 = 159783030
Therefore, the lowest common multiple of 454,990,891,790 is 159783030.
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.
454 x 990 x 891 x 790 = 316370399400
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.
454 : 1, 2, 227, 454
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
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,990,891,790, is 1.
Now, the common factors can be found like this.
454:2x 227
990:2x 3x 3x 5x 11
891:3x 3x 3x 3x 11
790:2x 5x 79
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 5x 11 = 1980
Therefore, the value for common factors is 1980.
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 = 316370399400/(1x1980)
LCM = 316370399400/1980
LCM = 159783030
Thus, we can understand that the LCM of 454,990,891,790 is 159783030.
