Given numbers are 689,187,831,481
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,187,831,481 is 3961535721.
Find LCM of 689,187,831,481 with Prime Factorization
| 13 | 689, 187, 831, 481 |
| 53, 187, 831, 37 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 187 x 831 x 37 = 3961535721
Therefore, the lowest common multiple of 689,187,831,481 is 3961535721.
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.
689 x 187 x 831 x 481 = 51499964373
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.
689 : 1, 13, 53, 689
187 : 1, 11, 17, 187
831 : 1, 3, 277, 831
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,187,831,481, is 1.
Now, the common factors can be found like this.
689:13x 53
187:11x 17
831:3x 277
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 51499964373/(1x13)
LCM = 51499964373/13
LCM = 3961535721
Thus, we can understand that the LCM of 689,187,831,481 is 3961535721.
