Find LCM of 813,576,256,380 with Prime Factorization
| 2 | 813, 576, 256, 380 |
| 2 | 813, 288, 128, 190 |
| 2 | 813, 144, 64, 95 |
| 2 | 813, 72, 32, 95 |
| 2 | 813, 36, 16, 95 |
| 2 | 813, 18, 8, 95 |
| 3 | 813, 9, 4, 95 |
| 271, 3, 4, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 271 x 3 x 4 x 95 = 59316480
Therefore, the lowest common multiple of 813,576,256,380 is 59316480.
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.
813 x 576 x 256 x 380 = 45555056640
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.
813 : 1, 3, 271, 813
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
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 813,576,256,380, is 1.
Now, the common factors can be found like this.
813:3x 271
576:2x 2x 2x 2x 2x 2x 3x 3
256:2x 2x 2x 2x 2x 2x 2x 2
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 2x 2x 2x 3 = 768
Therefore, the value for common factors is 768.
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 = 45555056640/(1x768)
LCM = 45555056640/768
LCM = 59316480
Thus, we can understand that the LCM of 813,576,256,380 is 59316480.
