Given numbers are 812,831,389,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,831,389,389 is 262486308.
Find LCM of 812,831,389,389 with Prime Factorization
389 | 812, 831, 389, 389 |
812, 831, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
389 x 812 x 831 x 1 x 1 = 262486308
Therefore, the lowest common multiple of 812,831,389,389 is 262486308.
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.
812 x 831 x 389 x 389 = 102107173812
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
831 : 1, 3, 277, 831
389 : 1, 389
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,831,389,389, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
831:3x 277
389:389
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
389 = 389
Therefore, the value for common factors is 389.
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 = 102107173812/(1x389)
LCM = 102107173812/389
LCM = 262486308
Thus, we can understand that the LCM of 812,831,389,389 is 262486308.
