Find LCM of 308,668,238,831,789 with Prime Factorization
| 2 | 308, 668, 238, 831, 789 |
| 2 | 154, 334, 119, 831, 789 |
| 3 | 77, 167, 119, 831, 789 |
| 7 | 77, 167, 119, 277, 263 |
| 11, 167, 17, 277, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 167 x 17 x 277 x 263 = 191105365836
Therefore, the lowest common multiple of 308,668,238,831,789 is 191105365836.
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.
308 x 668 x 238 x 831 x 789 = 32105701460448
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
668 : 1, 2, 4, 167, 334, 668
238 : 1, 2, 7, 14, 17, 34, 119, 238
831 : 1, 3, 277, 831
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,668,238,831,789, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
668:2x 2x 167
238:2x 7x 17
831:3x 277
789:3x 263
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 32105701460448/(1x168)
LCM = 32105701460448/168
LCM = 191105365836
Thus, we can understand that the LCM of 308,668,238,831,789 is 191105365836.
