Find LCM of 128,905,720,369,827 with Prime Factorization
| 2 | 128, 905, 720, 369, 827 |
| 2 | 64, 905, 360, 369, 827 |
| 2 | 32, 905, 180, 369, 827 |
| 2 | 16, 905, 90, 369, 827 |
| 3 | 8, 905, 45, 369, 827 |
| 3 | 8, 905, 15, 123, 827 |
| 5 | 8, 905, 5, 41, 827 |
| 8, 181, 1, 41, 827 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 8 x 181 x 1 x 41 x 827 = 35350081920
Therefore, the lowest common multiple of 128,905,720,369,827 is 35350081920.
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.
128 x 905 x 720 x 369 x 827 = 25452058982400
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
905 : 1, 5, 181, 905
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
369 : 1, 3, 9, 41, 123, 369
827 : 1, 827
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,905,720,369,827, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
905:5x 181
720:2x 2x 2x 2x 3x 3x 5
369:3x 3x 41
827:827
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 25452058982400/(1x720)
LCM = 25452058982400/720
LCM = 35350081920
Thus, we can understand that the LCM of 128,905,720,369,827 is 35350081920.
