Find LCM of 686,188,684,854,969 with Prime Factorization
| 2 | 686, 188, 684, 854, 969 |
| 2 | 343, 94, 342, 427, 969 |
| 3 | 343, 47, 171, 427, 969 |
| 7 | 343, 47, 57, 427, 323 |
| 19 | 49, 47, 57, 61, 323 |
| 49, 47, 3, 61, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 49 x 47 x 3 x 61 x 17 = 11434754268
Therefore, the lowest common multiple of 686,188,684,854,969 is 11434754268.
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 188 x 684 x 854 x 969 = 72999471246912
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
188 : 1, 2, 4, 47, 94, 188
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
854 : 1, 2, 7, 14, 61, 122, 427, 854
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,188,684,854,969, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
188:2x 2x 47
684:2x 2x 3x 3x 19
854:2x 7x 61
969:3x 17x 19
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 2x 3x 7x 19 = 6384
Therefore, the value for common factors is 6384.
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 = 72999471246912/(1x6384)
LCM = 72999471246912/6384
LCM = 11434754268
Thus, we can understand that the LCM of 686,188,684,854,969 is 11434754268.
