The LCM of 867,760,120,255 is 658920.
Find LCM of 867,760,120,255 with Prime Factorization
| 2 | 867, 760, 120, 255 |
| 2 | 867, 380, 60, 255 |
| 2 | 867, 190, 30, 255 |
| 3 | 867, 95, 15, 255 |
| 5 | 289, 95, 5, 85 |
| 17 | 289, 19, 1, 17 |
| 1, 19, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 17 x 1 x 19 x 1 x 17 = 658920
Therefore, the lowest common multiple of 867,760,120,255 is 658920.
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.
867 x 760 x 120 x 255 = 20162952000
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.
867 : 1, 3, 17, 51, 289, 867
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,760,120,255, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
760:2x 2x 2x 5x 19
120:2x 2x 2x 3x 5
255:3x 5x 17
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 2x 3x 3x 5x 5x 17 = 30600
Therefore, the value for common factors is 30600.
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 = 20162952000/(1x30600)
LCM = 20162952000/30600
LCM = 658920
Thus, we can understand that the LCM of 867,760,120,255 is 658920.
