Find LCM of 405,128,480,922 with Prime Factorization
| 2 | 405, 128, 480, 922 |
| 2 | 405, 64, 240, 461 |
| 2 | 405, 32, 120, 461 |
| 2 | 405, 16, 60, 461 |
| 2 | 405, 8, 30, 461 |
| 3 | 405, 4, 15, 461 |
| 5 | 135, 4, 5, 461 |
| 27, 4, 1, 461 |
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 27 x 4 x 1 x 461 = 23898240
Therefore, the lowest common multiple of 405,128,480,922 is 23898240.
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.
405 x 128 x 480 x 922 = 22942310400
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
128 : 1, 2, 4, 8, 16, 32, 64, 128
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
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,128,480,922, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
128:2x 2x 2x 2x 2x 2x 2
480:2x 2x 2x 2x 2x 3x 5
922:2x 461
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 5 = 960
Therefore, the value for common factors is 960.
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 = 22942310400/(1x960)
LCM = 22942310400/960
LCM = 23898240
Thus, we can understand that the LCM of 405,128,480,922 is 23898240.
