Given numbers are 779,819,181,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,819,181,455 is 577390905.
Find LCM of 779,819,181,455 with Prime Factorization
| 7 | 779, 819, 181, 455 |
| 13 | 779, 117, 181, 65 |
| 779, 9, 181, 5 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 779 x 9 x 181 x 5 = 577390905
Therefore, the lowest common multiple of 779,819,181,455 is 577390905.
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.
779 x 819 x 181 x 455 = 52542572355
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.
779 : 1, 19, 41, 779
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
181 : 1, 181
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,819,181,455, is 1.
Now, the common factors can be found like this.
779:19x 41
819:3x 3x 7x 13
181:181
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13 = 91
Therefore, the value for common factors is 91.
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 = 52542572355/(1x91)
LCM = 52542572355/91
LCM = 577390905
Thus, we can understand that the LCM of 779,819,181,455 is 577390905.
