Find LCM of 867,923,117,819,987 with Prime Factorization
| 3 | 867, 923, 117, 819, 987 |
| 3 | 289, 923, 39, 273, 329 |
| 7 | 289, 923, 13, 91, 329 |
| 13 | 289, 923, 13, 13, 47 |
| 289, 71, 1, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 13 x 289 x 71 x 1 x 1 x 47 = 789837867
Therefore, the lowest common multiple of 867,923,117,819,987 is 789837867.
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.
867 x 923 x 117 x 819 x 987 = 75684633929541
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.
867 : 1, 3, 17, 51, 289, 867
923 : 1, 13, 71, 923
117 : 1, 3, 9, 13, 39, 117
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,923,117,819,987, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
923:13x 71
117:3x 3x 13
819:3x 3x 7x 13
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 7x 13x 13 = 95823
Therefore, the value for common factors is 95823.
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 = 75684633929541/(1x95823)
LCM = 75684633929541/95823
LCM = 789837867
Thus, we can understand that the LCM of 867,923,117,819,987 is 789837867.
