Given numbers are 169,809,946,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,809,946,559 is 129338066.
Find LCM of 169,809,946,559 with Prime Factorization
| 13 | 169, 809, 946, 559 |
| 43 | 13, 809, 946, 43 |
| 13, 809, 22, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 43 x 13 x 809 x 22 x 1 = 129338066
Therefore, the lowest common multiple of 169,809,946,559 is 129338066.
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.
169 x 809 x 946 x 559 = 72299978894
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.
169 : 1, 13, 169
809 : 1, 809
946 : 1, 2, 11, 22, 43, 86, 473, 946
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,809,946,559, is 1.
Now, the common factors can be found like this.
169:13x 13
809:809
946:2x 11x 43
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 43 = 559
Therefore, the value for common factors is 559.
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 = 72299978894/(1x559)
LCM = 72299978894/559
LCM = 129338066
Thus, we can understand that the LCM of 169,809,946,559 is 129338066.
