Find LCM of 684,729,551,686,699 with Prime Factorization
| 2 | 684, 729, 551, 686, 699 |
| 3 | 342, 729, 551, 343, 699 |
| 3 | 114, 243, 551, 343, 233 |
| 19 | 38, 81, 551, 343, 233 |
| 2, 81, 29, 343, 233 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 2 x 81 x 29 x 343 x 233 = 128407136004
Therefore, the lowest common multiple of 684,729,551,686,699 is 128407136004.
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 729 x 551 x 686 x 699 = 131745721540104
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
729 : 1, 3, 9, 27, 81, 243, 729
551 : 1, 19, 29, 551
686 : 1, 2, 7, 14, 49, 98, 343, 686
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,729,551,686,699, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
729:3x 3x 3x 3x 3x 3
551:19x 29
686:2x 7x 7x 7
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 19 = 1026
Therefore, the value for common factors is 1026.
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 = 131745721540104/(1x1026)
LCM = 131745721540104/1026
LCM = 128407136004
Thus, we can understand that the LCM of 684,729,551,686,699 is 128407136004.
