The LCM of 342,988,416,857 is 60963552.
Find LCM of 342,988,416,857 with Prime Factorization
| 2 | 342, 988, 416, 857 |
| 2 | 171, 494, 208, 857 |
| 13 | 171, 247, 104, 857 |
| 19 | 171, 19, 8, 857 |
| 9, 1, 8, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 9 x 1 x 8 x 857 = 60963552
Therefore, the lowest common multiple of 342,988,416,857 is 60963552.
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.
342 x 988 x 416 x 857 = 120463978752
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,988,416,857, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
988:2x 2x 13x 19
416:2x 2x 2x 2x 2x 13
857:857
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 120463978752/(1x1976)
LCM = 120463978752/1976
LCM = 60963552
Thus, we can understand that the LCM of 342,988,416,857 is 60963552.
