Find LCM of 813,318,480,765,512 with Prime Factorization
| 2 | 813, 318, 480, 765, 512 |
| 2 | 813, 159, 240, 765, 256 |
| 2 | 813, 159, 120, 765, 128 |
| 2 | 813, 159, 60, 765, 64 |
| 2 | 813, 159, 30, 765, 32 |
| 3 | 813, 159, 15, 765, 16 |
| 5 | 271, 53, 5, 255, 16 |
| 271, 53, 1, 51, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 271 x 53 x 1 x 51 x 16 = 5625699840
Therefore, the lowest common multiple of 813,318,480,765,512 is 5625699840.
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 318 x 480 x 765 x 512 = 48606046617600
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
318 : 1, 2, 3, 6, 53, 106, 159, 318
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,318,480,765,512, is 1.
Now, the common factors can be found like this.
813:3x 271
318:2x 3x 53
480:2x 2x 2x 2x 2x 3x 5
765:3x 3x 5x 17
512:2x 2x 2x 2x 2x 2x 2x 2x 2
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 3x 3x 3x 5 = 8640
Therefore, the value for common factors is 8640.
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 = 48606046617600/(1x8640)
LCM = 48606046617600/8640
LCM = 5625699840
Thus, we can understand that the LCM of 813,318,480,765,512 is 5625699840.
