The LCM of 323,129,305,680,747 is 25315202520.
Find LCM of 323,129,305,680,747 with Prime Factorization
| 3 | 323, 129, 305, 680, 747 |
| 5 | 323, 43, 305, 680, 249 |
| 17 | 323, 43, 61, 136, 249 |
| 19, 43, 61, 8, 249 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 19 x 43 x 61 x 8 x 249 = 25315202520
Therefore, the lowest common multiple of 323,129,305,680,747 is 25315202520.
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.
323 x 129 x 305 x 680 x 747 = 6455376642600
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.
323 : 1, 17, 19, 323
129 : 1, 3, 43, 129
305 : 1, 5, 61, 305
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,129,305,680,747, is 1.
Now, the common factors can be found like this.
323:17x 19
129:3x 43
305:5x 61
680:2x 2x 2x 5x 17
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17 = 255
Therefore, the value for common factors is 255.
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 = 6455376642600/(1x255)
LCM = 6455376642600/255
LCM = 25315202520
Thus, we can understand that the LCM of 323,129,305,680,747 is 25315202520.
