Find LCM of 305,819,966,793,891 with Prime Factorization
3 | 305, 819, 966, 793, 891 |
3 | 305, 273, 322, 793, 297 |
7 | 305, 91, 322, 793, 99 |
13 | 305, 13, 46, 793, 99 |
61 | 305, 1, 46, 61, 99 |
5, 1, 46, 1, 99 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 13 x 61 x 5 x 1 x 46 x 1 x 99 = 1137566430
Therefore, the lowest common multiple of 305,819,966,793,891 is 1137566430.
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.
305 x 819 x 966 x 793 x 891 = 170495043829110
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.
305 : 1, 5, 61, 305
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
793 : 1, 13, 61, 793
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,819,966,793,891, is 1.
Now, the common factors can be found like this.
305:5x 61
819:3x 3x 7x 13
966:2x 3x 7x 23
793:13x 61
891:3x 3x 3x 3x 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 13x 61 = 149877
Therefore, the value for common factors is 149877.
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 = 170495043829110/(1x149877)
LCM = 170495043829110/149877
LCM = 1137566430
Thus, we can understand that the LCM of 305,819,966,793,891 is 1137566430.
