Find LCM of 928,806,505,320,654 with Prime Factorization
| 2 | 928, 806, 505, 320, 654 |
| 2 | 464, 403, 505, 160, 327 |
| 2 | 232, 403, 505, 80, 327 |
| 2 | 116, 403, 505, 40, 327 |
| 2 | 58, 403, 505, 20, 327 |
| 5 | 29, 403, 505, 10, 327 |
| 29, 403, 101, 2, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 29 x 403 x 101 x 2 x 327 = 123515695680
Therefore, the lowest common multiple of 928,806,505,320,654 is 123515695680.
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.
928 x 806 x 505 x 320 x 654 = 79050045235200
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.
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
806 : 1, 2, 13, 26, 31, 62, 403, 806
505 : 1, 5, 101, 505
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 928,806,505,320,654, is 1.
Now, the common factors can be found like this.
928:2x 2x 2x 2x 2x 29
806:2x 13x 31
505:5x 101
320:2x 2x 2x 2x 2x 2x 5
654:2x 3x 109
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 5 = 640
Therefore, the value for common factors is 640.
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 = 79050045235200/(1x640)
LCM = 79050045235200/640
LCM = 123515695680
Thus, we can understand that the LCM of 928,806,505,320,654 is 123515695680.
