Find LCM of 268,240,646,160,557 with Prime Factorization
| 2 | 268, 240, 646, 160, 557 |
| 2 | 134, 120, 323, 80, 557 |
| 2 | 67, 60, 323, 40, 557 |
| 2 | 67, 30, 323, 20, 557 |
| 5 | 67, 15, 323, 10, 557 |
| 67, 3, 323, 2, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 67 x 3 x 323 x 2 x 557 = 5785937760
Therefore, the lowest common multiple of 268,240,646,160,557 is 5785937760.
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 240 x 646 x 160 x 557 = 3703000166400
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
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
646 : 1, 2, 17, 19, 34, 38, 323, 646
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,240,646,160,557, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
240:2x 2x 2x 2x 3x 5
646:2x 17x 19
160:2x 2x 2x 2x 2x 5
557:557
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 = 3703000166400/(1x640)
LCM = 3703000166400/640
LCM = 5785937760
Thus, we can understand that the LCM of 268,240,646,160,557 is 5785937760.
