Given numbers are 683,786,831,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 683,786,831,991 is 147365788866.
Find LCM of 683,786,831,991 with Prime Factorization
| 3 | 683, 786, 831, 991 |
| 683, 262, 277, 991 |
Multiply the prime numbers at the bottom and the left side.
3 x 683 x 262 x 277 x 991 = 147365788866
Therefore, the lowest common multiple of 683,786,831,991 is 147365788866.
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.
683 x 786 x 831 x 991 = 442097366598
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.
683 : 1, 683
786 : 1, 2, 3, 6, 131, 262, 393, 786
831 : 1, 3, 277, 831
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,786,831,991, is 1.
Now, the common factors can be found like this.
683:683
786:2x 3x 131
831:3x 277
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 442097366598/(1x3)
LCM = 442097366598/3
LCM = 147365788866
Thus, we can understand that the LCM of 683,786,831,991 is 147365788866.
