Find LCM of 682,867,920,942,385 with Prime Factorization
| 2 | 682, 867, 920, 942, 385 |
| 3 | 341, 867, 460, 471, 385 |
| 5 | 341, 289, 460, 157, 385 |
| 11 | 341, 289, 92, 157, 77 |
| 31, 289, 92, 157, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 31 x 289 x 92 x 157 x 7 = 298922768760
Therefore, the lowest common multiple of 682,867,920,942,385 is 298922768760.
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.
682 x 867 x 920 x 942 x 385 = 197289027381600
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
867 : 1, 3, 17, 51, 289, 867
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
942 : 1, 2, 3, 6, 157, 314, 471, 942
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,867,920,942,385, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
867:3x 17x 17
920:2x 2x 2x 5x 23
942:2x 3x 157
385:5x 7x 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 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 197289027381600/(1x660)
LCM = 197289027381600/660
LCM = 298922768760
Thus, we can understand that the LCM of 682,867,920,942,385 is 298922768760.
