The LCM of 113,428,791,428,838 is 141851612.
Find LCM of 113,428,791,428,838 with Prime Factorization
| 2 | 113, 428, 791, 428, 838 |
| 2 | 113, 214, 791, 214, 419 |
| 107 | 113, 107, 791, 107, 419 |
| 113 | 113, 1, 791, 1, 419 |
| 1, 1, 7, 1, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 107 x 113 x 1 x 1 x 7 x 1 x 419 = 141851612
Therefore, the lowest common multiple of 113,428,791,428,838 is 141851612.
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.
113 x 428 x 791 x 428 x 838 = 13721022725536
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.
113 : 1, 113
428 : 1, 2, 4, 107, 214, 428
791 : 1, 7, 113, 791
428 : 1, 2, 4, 107, 214, 428
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 113,428,791,428,838, is 1.
Now, the common factors can be found like this.
113:113
428:2x 2x 107
791:7x 113
428:2x 2x 107
838:2x 419
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 107x 113 = 96728
Therefore, the value for common factors is 96728.
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 = 13721022725536/(1x96728)
LCM = 13721022725536/96728
LCM = 141851612
Thus, we can understand that the LCM of 113,428,791,428,838 is 141851612.
