Given numbers are 455,855,916,969,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,855,916,969,447 is 180525339540.
Find LCM of 455,855,916,969,447 with Prime Factorization
| 3 | 455, 855, 916, 969, 447 |
| 5 | 455, 285, 916, 323, 149 |
| 19 | 91, 57, 916, 323, 149 |
| 91, 3, 916, 17, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 91 x 3 x 916 x 17 x 149 = 180525339540
Therefore, the lowest common multiple of 455,855,916,969,447 is 180525339540.
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.
455 x 855 x 916 x 969 x 447 = 154349165306700
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
916 : 1, 2, 4, 229, 458, 916
969 : 1, 3, 17, 19, 51, 57, 323, 969
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,855,916,969,447, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
855:3x 3x 5x 19
916:2x 2x 229
969:3x 17x 19
447:3x 149
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 5x 19 = 855
Therefore, the value for common factors is 855.
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 = 154349165306700/(1x855)
LCM = 154349165306700/855
LCM = 180525339540
Thus, we can understand that the LCM of 455,855,916,969,447 is 180525339540.
