Find LCM of 220,384,640,317 with Prime Factorization
| 2 | 220, 384, 640, 317 |
| 2 | 110, 192, 320, 317 |
| 2 | 55, 96, 160, 317 |
| 2 | 55, 48, 80, 317 |
| 2 | 55, 24, 40, 317 |
| 2 | 55, 12, 20, 317 |
| 2 | 55, 6, 10, 317 |
| 5 | 55, 3, 5, 317 |
| 11, 3, 1, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 5 x 11 x 3 x 1 x 317 = 6695040
Therefore, the lowest common multiple of 220,384,640,317 is 6695040.
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.
220 x 384 x 640 x 317 = 17139302400
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
317 : 1, 317
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,384,640,317, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
384:2x 2x 2x 2x 2x 2x 2x 3
640:2x 2x 2x 2x 2x 2x 2x 5
317:317
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 2x 5 = 2560
Therefore, the value for common factors is 2560.
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 = 17139302400/(1x2560)
LCM = 17139302400/2560
LCM = 6695040
Thus, we can understand that the LCM of 220,384,640,317 is 6695040.
