Given numbers are 831,643,554,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,643,554,447 is 159231234.
Find LCM of 831,643,554,447 with Prime Factorization
| 3 | 831, 643, 554, 447 |
| 277 | 277, 643, 554, 149 |
| 1, 643, 2, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 277 x 1 x 643 x 2 x 149 = 159231234
Therefore, the lowest common multiple of 831,643,554,447 is 159231234.
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.
831 x 643 x 554 x 447 = 132321155454
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.
831 : 1, 3, 277, 831
643 : 1, 643
554 : 1, 2, 277, 554
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,643,554,447, is 1.
Now, the common factors can be found like this.
831:3x 277
643:643
554:2x 277
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 277 = 831
Therefore, the value for common factors is 831.
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 = 132321155454/(1x831)
LCM = 132321155454/831
LCM = 159231234
Thus, we can understand that the LCM of 831,643,554,447 is 159231234.
