Find LCM of 809,819,903,378,847 with Prime Factorization
3 | 809, 819, 903, 378, 847 |
3 | 809, 273, 301, 126, 847 |
7 | 809, 91, 301, 42, 847 |
809, 13, 43, 6, 121 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 809 x 13 x 43 x 6 x 121 = 20684141478
Therefore, the lowest common multiple of 809,819,903,378,847 is 20684141478.
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.
809 x 819 x 903 x 378 x 847 = 191555834227758
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.
809 : 1, 809
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
903 : 1, 3, 7, 21, 43, 129, 301, 903
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,819,903,378,847, is 1.
Now, the common factors can be found like this.
809:809
819:3x 3x 7x 13
903:3x 7x 43
378:2x 3x 3x 3x 7
847:7x 11x 11
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 7x 7x 7 = 9261
Therefore, the value for common factors is 9261.
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 = 191555834227758/(1x9261)
LCM = 191555834227758/9261
LCM = 20684141478
Thus, we can understand that the LCM of 809,819,903,378,847 is 20684141478.
