Find LCM of 268,640,581,960 with Prime Factorization
| 2 | 268, 640, 581, 960 |
| 2 | 134, 320, 581, 480 |
| 2 | 67, 160, 581, 240 |
| 2 | 67, 80, 581, 120 |
| 2 | 67, 40, 581, 60 |
| 2 | 67, 20, 581, 30 |
| 5 | 67, 10, 581, 15 |
| 67, 2, 581, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 5 x 67 x 2 x 581 x 3 = 74739840
Therefore, the lowest common multiple of 268,640,581,960 is 74739840.
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.
268 x 640 x 581 x 960 = 95666995200
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.
268 : 1, 2, 4, 67, 134, 268
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
581 : 1, 7, 83, 581
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,640,581,960, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
640:2x 2x 2x 2x 2x 2x 2x 5
581:7x 83
960:2x 2x 2x 2x 2x 2x 3x 5
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 5 = 1280
Therefore, the value for common factors is 1280.
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 = 95666995200/(1x1280)
LCM = 95666995200/1280
LCM = 74739840
Thus, we can understand that the LCM of 268,640,581,960 is 74739840.
