Find LCM of 391,850,905,783,822 with Prime Factorization
| 2 | 391, 850, 905, 783, 822 |
| 3 | 391, 425, 905, 783, 411 |
| 5 | 391, 425, 905, 261, 137 |
| 17 | 391, 85, 181, 261, 137 |
| 23, 5, 181, 261, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 23 x 5 x 181 x 261 x 137 = 379583797050
Therefore, the lowest common multiple of 391,850,905,783,822 is 379583797050.
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.
391 x 850 x 905 x 783 x 822 = 193587736495500
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.
391 : 1, 17, 23, 391
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
905 : 1, 5, 181, 905
783 : 1, 3, 9, 27, 29, 87, 261, 783
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,850,905,783,822, is 1.
Now, the common factors can be found like this.
391:17x 23
850:2x 5x 5x 17
905:5x 181
783:3x 3x 3x 29
822:2x 3x 137
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 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 193587736495500/(1x510)
LCM = 193587736495500/510
LCM = 379583797050
Thus, we can understand that the LCM of 391,850,905,783,822 is 379583797050.
