The LCM of 239,486,198,781,308 is 1270027836.
Find LCM of 239,486,198,781,308 with Prime Factorization
| 2 | 239, 486, 198, 781, 308 |
| 3 | 239, 243, 99, 781, 154 |
| 3 | 239, 81, 33, 781, 154 |
| 11 | 239, 27, 11, 781, 154 |
| 239, 27, 1, 71, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 239 x 27 x 1 x 71 x 14 = 1270027836
Therefore, the lowest common multiple of 239,486,198,781,308 is 1270027836.
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.
239 x 486 x 198 x 781 x 308 = 5532241253616
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.
239 : 1, 239
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
781 : 1, 11, 71, 781
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,486,198,781,308, is 1.
Now, the common factors can be found like this.
239:239
486:2x 3x 3x 3x 3x 3
198:2x 3x 3x 11
781:11x 71
308:2x 2x 7x 11
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 3x 3x 11x 11 = 4356
Therefore, the value for common factors is 4356.
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 = 5532241253616/(1x4356)
LCM = 5532241253616/4356
LCM = 1270027836
Thus, we can understand that the LCM of 239,486,198,781,308 is 1270027836.
