Find LCM of 689,580,696,261,656 with Prime Factorization
2 | 689, 580, 696, 261, 656 |
2 | 689, 290, 348, 261, 328 |
2 | 689, 145, 174, 261, 164 |
3 | 689, 145, 87, 261, 82 |
29 | 689, 145, 29, 87, 82 |
689, 5, 1, 3, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 29 x 689 x 5 x 1 x 3 x 82 = 589839120
Therefore, the lowest common multiple of 689,580,696,261,656 is 589839120.
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.
689 x 580 x 696 x 261 x 656 = 47621251192320
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.
689 : 1, 13, 53, 689
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
261 : 1, 3, 9, 29, 87, 261
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,580,696,261,656, is 1.
Now, the common factors can be found like this.
689:13x 53
580:2x 2x 5x 29
696:2x 2x 2x 3x 29
261:3x 3x 29
656:2x 2x 2x 2x 41
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 2x 3x 29x 29 = 80736
Therefore, the value for common factors is 80736.
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 = 47621251192320/(1x80736)
LCM = 47621251192320/80736
LCM = 589839120
Thus, we can understand that the LCM of 689,580,696,261,656 is 589839120.
