Find LCM of 261,355,880,286,783 with Prime Factorization
| 2 | 261, 355, 880, 286, 783 |
| 3 | 261, 355, 440, 143, 783 |
| 3 | 87, 355, 440, 143, 261 |
| 5 | 29, 355, 440, 143, 87 |
| 11 | 29, 71, 88, 143, 87 |
| 29 | 29, 71, 8, 13, 87 |
| 1, 71, 8, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 29 x 1 x 71 x 8 x 13 x 3 = 635983920
Therefore, the lowest common multiple of 261,355,880,286,783 is 635983920.
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.
261 x 355 x 880 x 286 x 783 = 18259098343200
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.
261 : 1, 3, 9, 29, 87, 261
355 : 1, 5, 71, 355
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
286 : 1, 2, 11, 13, 22, 26, 143, 286
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,355,880,286,783, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
355:5x 71
880:2x 2x 2x 2x 5x 11
286:2x 11x 13
783:3x 3x 3x 29
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 5x 11x 29 = 28710
Therefore, the value for common factors is 28710.
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 = 18259098343200/(1x28710)
LCM = 18259098343200/28710
LCM = 635983920
Thus, we can understand that the LCM of 261,355,880,286,783 is 635983920.
