Given numbers are 831,201,913,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,201,913,871 is 660830313.
Find LCM of 831,201,913,871 with Prime Factorization
| 3 | 831, 201, 913, 871 |
| 67 | 277, 67, 913, 871 |
| 277, 1, 913, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 67 x 277 x 1 x 913 x 13 = 660830313
Therefore, the lowest common multiple of 831,201,913,871 is 660830313.
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 201 x 913 x 871 = 132826892913
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
201 : 1, 3, 67, 201
913 : 1, 11, 83, 913
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,201,913,871, is 1.
Now, the common factors can be found like this.
831:3x 277
201:3x 67
913:11x 83
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 67 = 201
Therefore, the value for common factors is 201.
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 = 132826892913/(1x201)
LCM = 132826892913/201
LCM = 660830313
Thus, we can understand that the LCM of 831,201,913,871 is 660830313.
