Given numbers are 843,384,428,665,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,384,428,665,447 is 1144008458880.
Find LCM of 843,384,428,665,447 with Prime Factorization
| 2 | 843, 384, 428, 665, 447 |
| 2 | 843, 192, 214, 665, 447 |
| 3 | 843, 96, 107, 665, 447 |
| 281, 32, 107, 665, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 281 x 32 x 107 x 665 x 149 = 1144008458880
Therefore, the lowest common multiple of 843,384,428,665,447 is 1144008458880.
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.
843 x 384 x 428 x 665 x 447 = 41184304519680
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.
843 : 1, 3, 281, 843
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
428 : 1, 2, 4, 107, 214, 428
665 : 1, 5, 7, 19, 35, 95, 133, 665
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,384,428,665,447, is 1.
Now, the common factors can be found like this.
843:3x 281
384:2x 2x 2x 2x 2x 2x 2x 3
428:2x 2x 107
665:5x 7x 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.
2x 2x 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 41184304519680/(1x36)
LCM = 41184304519680/36
LCM = 1144008458880
Thus, we can understand that the LCM of 843,384,428,665,447 is 1144008458880.
