Find LCM of 819,858,686,934,172 with Prime Factorization
| 2 | 819, 858, 686, 934, 172 |
| 3 | 819, 429, 343, 467, 86 |
| 7 | 273, 143, 343, 467, 86 |
| 13 | 39, 143, 49, 467, 86 |
| 3, 11, 49, 467, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 3 x 11 x 49 x 467 x 86 = 35458306884
Therefore, the lowest common multiple of 819,858,686,934,172 is 35458306884.
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.
819 x 858 x 686 x 934 x 172 = 77440942234656
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
686 : 1, 2, 7, 14, 49, 98, 343, 686
934 : 1, 2, 467, 934
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,858,686,934,172, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
858:2x 3x 11x 13
686:2x 7x 7x 7
934:2x 467
172:2x 2x 43
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 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 77440942234656/(1x2184)
LCM = 77440942234656/2184
LCM = 35458306884
Thus, we can understand that the LCM of 819,858,686,934,172 is 35458306884.
