Find LCM of 684,704,836,343,137 with Prime Factorization
| 2 | 684, 704, 836, 343, 137 |
| 2 | 342, 352, 418, 343, 137 |
| 11 | 171, 176, 209, 343, 137 |
| 19 | 171, 16, 19, 343, 137 |
| 9, 16, 1, 343, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 9 x 16 x 1 x 343 x 137 = 5656964544
Therefore, the lowest common multiple of 684,704,836,343,137 is 5656964544.
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.
684 x 704 x 836 x 343 x 137 = 18916889435136
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
343 : 1, 7, 49, 343
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,704,836,343,137, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
704:2x 2x 2x 2x 2x 2x 11
836:2x 2x 11x 19
343:7x 7x 7
137:137
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 11x 19 = 3344
Therefore, the value for common factors is 3344.
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 = 18916889435136/(1x3344)
LCM = 18916889435136/3344
LCM = 5656964544
Thus, we can understand that the LCM of 684,704,836,343,137 is 5656964544.
