Given numbers are 843,791,672,333,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,791,672,333,831 is 656079977952.
Find LCM of 843,791,672,333,831 with Prime Factorization
| 3 | 843, 791, 672, 333, 831 |
| 7 | 281, 791, 224, 111, 277 |
| 281, 113, 32, 111, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 281 x 113 x 32 x 111 x 277 = 656079977952
Therefore, the lowest common multiple of 843,791,672,333,831 is 656079977952.
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 791 x 672 x 333 x 831 = 123999115832928
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
791 : 1, 7, 113, 791
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
333 : 1, 3, 9, 37, 111, 333
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,791,672,333,831, is 1.
Now, the common factors can be found like this.
843:3x 281
791:7x 113
672:2x 2x 2x 2x 2x 3x 7
333:3x 3x 37
831:3x 277
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 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 123999115832928/(1x189)
LCM = 123999115832928/189
LCM = 656079977952
Thus, we can understand that the LCM of 843,791,672,333,831 is 656079977952.
