Given numbers are 831,898,705,787,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,898,705,787,760 is 10488987005160.
Find LCM of 831,898,705,787,760 with Prime Factorization
| 2 | 831, 898, 705, 787, 760 |
| 3 | 831, 449, 705, 787, 380 |
| 5 | 277, 449, 235, 787, 380 |
| 277, 449, 47, 787, 76 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 449 x 47 x 787 x 76 = 10488987005160
Therefore, the lowest common multiple of 831,898,705,787,760 is 10488987005160.
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 898 x 705 x 787 x 760 = 314669610154800
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
898 : 1, 2, 449, 898
705 : 1, 3, 5, 15, 47, 141, 235, 705
787 : 1, 787
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,898,705,787,760, is 1.
Now, the common factors can be found like this.
831:3x 277
898:2x 449
705:3x 5x 47
787:787
760:2x 2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 314669610154800/(1x30)
LCM = 314669610154800/30
LCM = 10488987005160
Thus, we can understand that the LCM of 831,898,705,787,760 is 10488987005160.
