The LCM of 511,456,720,380 is 6990480.
Find LCM of 511,456,720,380 with Prime Factorization
| 2 | 511, 456, 720, 380 |
| 2 | 511, 228, 360, 190 |
| 2 | 511, 114, 180, 95 |
| 3 | 511, 57, 90, 95 |
| 5 | 511, 19, 30, 95 |
| 19 | 511, 19, 6, 19 |
| 511, 1, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 19 x 511 x 1 x 6 x 1 = 6990480
Therefore, the lowest common multiple of 511,456,720,380 is 6990480.
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.
511 x 456 x 720 x 380 = 63753177600
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.
511 : 1, 7, 73, 511
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
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 511,456,720,380, is 1.
Now, the common factors can be found like this.
511:7x 73
456:2x 2x 2x 3x 19
720:2x 2x 2x 2x 3x 3x 5
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 2x 2x 2x 3x 5x 19 = 9120
Therefore, the value for common factors is 9120.
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 = 63753177600/(1x9120)
LCM = 63753177600/9120
LCM = 6990480
Thus, we can understand that the LCM of 511,456,720,380 is 6990480.
