The LCM of 686,199,252,885,872 is 158025876120.
Find LCM of 686,199,252,885,872 with Prime Factorization
| 2 | 686, 199, 252, 885, 872 |
| 2 | 343, 199, 126, 885, 436 |
| 3 | 343, 199, 63, 885, 218 |
| 7 | 343, 199, 21, 295, 218 |
| 49, 199, 3, 295, 218 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 49 x 199 x 3 x 295 x 218 = 158025876120
Therefore, the lowest common multiple of 686,199,252,885,872 is 158025876120.
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.
686 x 199 x 252 x 885 x 872 = 26548347188160
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
199 : 1, 199
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
885 : 1, 3, 5, 15, 59, 177, 295, 885
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,199,252,885,872, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
199:199
252:2x 2x 3x 3x 7
885:3x 5x 59
872:2x 2x 2x 109
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 = 26548347188160/(1x168)
LCM = 26548347188160/168
LCM = 158025876120
Thus, we can understand that the LCM of 686,199,252,885,872 is 158025876120.
