The LCM of 311,277,760,380 is 65471720.
Find LCM of 311,277,760,380 with Prime Factorization
| 2 | 311, 277, 760, 380 |
| 2 | 311, 277, 380, 190 |
| 5 | 311, 277, 95, 190 |
| 19 | 311, 277, 19, 38 |
| 311, 277, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 311 x 277 x 1 x 2 = 65471720
Therefore, the lowest common multiple of 311,277,760,380 is 65471720.
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.
311 x 277 x 760 x 380 = 24879253600
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.
311 : 1, 311
277 : 1, 277
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,277,760,380, is 1.
Now, the common factors can be found like this.
311:311
277:277
760:2x 2x 2x 5x 19
380:2x 2x 5x 19
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 24879253600/(1x380)
LCM = 24879253600/380
LCM = 65471720
Thus, we can understand that the LCM of 311,277,760,380 is 65471720.
