Find LCM of 667,459,128,682,990 with Prime Factorization
| 2 | 667, 459, 128, 682, 990 |
| 3 | 667, 459, 64, 341, 495 |
| 3 | 667, 153, 64, 341, 165 |
| 11 | 667, 51, 64, 341, 55 |
| 667, 51, 64, 31, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 667 x 51 x 64 x 31 x 5 = 66814830720
Therefore, the lowest common multiple of 667,459,128,682,990 is 66814830720.
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.
667 x 459 x 128 x 682 x 990 = 26458672965120
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.
667 : 1, 23, 29, 667
459 : 1, 3, 9, 17, 27, 51, 153, 459
128 : 1, 2, 4, 8, 16, 32, 64, 128
682 : 1, 2, 11, 22, 31, 62, 341, 682
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,459,128,682,990, is 1.
Now, the common factors can be found like this.
667:23x 29
459:3x 3x 3x 17
128:2x 2x 2x 2x 2x 2x 2
682:2x 11x 31
990:2x 3x 3x 5x 11
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 11 = 396
Therefore, the value for common factors is 396.
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 = 26458672965120/(1x396)
LCM = 26458672965120/396
LCM = 66814830720
Thus, we can understand that the LCM of 667,459,128,682,990 is 66814830720.
