Find LCM of 682,969,114,561,690 with Prime Factorization
| 2 | 682, 969, 114, 561, 690 |
| 3 | 341, 969, 57, 561, 345 |
| 11 | 341, 323, 19, 187, 115 |
| 17 | 31, 323, 19, 17, 115 |
| 19 | 31, 19, 19, 1, 115 |
| 31, 1, 1, 1, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 19 x 31 x 1 x 1 x 1 x 115 = 75998670
Therefore, the lowest common multiple of 682,969,114,561,690 is 75998670.
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.
682 x 969 x 114 x 561 x 690 = 29162513647080
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
969 : 1, 3, 17, 19, 51, 57, 323, 969
114 : 1, 2, 3, 6, 19, 38, 57, 114
561 : 1, 3, 11, 17, 33, 51, 187, 561
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,969,114,561,690, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
969:3x 17x 19
114:2x 3x 19
561:3x 11x 17
690:2x 3x 5x 23
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 3x 3x 3x 11x 17x 19 = 383724
Therefore, the value for common factors is 383724.
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 = 29162513647080/(1x383724)
LCM = 29162513647080/383724
LCM = 75998670
Thus, we can understand that the LCM of 682,969,114,561,690 is 75998670.
