Given numbers are 579,921,678,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,921,678,447 is 5985654522.
Find LCM of 579,921,678,447 with Prime Factorization
| 3 | 579, 921, 678, 447 |
| 193, 307, 226, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 193 x 307 x 226 x 149 = 5985654522
Therefore, the lowest common multiple of 579,921,678,447 is 5985654522.
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.
579 x 921 x 678 x 447 = 161612672094
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.
579 : 1, 3, 193, 579
921 : 1, 3, 307, 921
678 : 1, 2, 3, 6, 113, 226, 339, 678
447 : 1, 3, 149, 447
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,921,678,447, is 3.
Now, the common factors can be found like this.
579:3x 193
921:3x 307
678:2x 3x 113
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 3 = 9
Therefore, the value for common factors is 9.
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 = 161612672094/(3x9)
LCM = 161612672094/27
LCM = 5985654522
Thus, we can understand that the LCM of 579,921,678,447 is 5985654522.
