The LCM of 680,512,908,832 is 128427520.
Find LCM of 680,512,908,832 with Prime Factorization
| 2 | 680, 512, 908, 832 |
| 2 | 340, 256, 454, 416 |
| 2 | 170, 128, 227, 208 |
| 2 | 85, 64, 227, 104 |
| 2 | 85, 32, 227, 52 |
| 2 | 85, 16, 227, 26 |
| 85, 8, 227, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 85 x 8 x 227 x 13 = 128427520
Therefore, the lowest common multiple of 680,512,908,832 is 128427520.
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.
680 x 512 x 908 x 832 = 263019560960
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
908 : 1, 2, 4, 227, 454, 908
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,512,908,832, is 4.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
512:2x 2x 2x 2x 2x 2x 2x 2x 2
908:2x 2x 227
832:2x 2x 2x 2x 2x 2x 13
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 2 = 512
Therefore, the value for common factors is 512.
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 = 263019560960/(4x512)
LCM = 263019560960/2048
LCM = 128427520
Thus, we can understand that the LCM of 680,512,908,832 is 128427520.
