Given numbers are 891,283,961,813,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,283,961,813,657 is 4793797429839.
Find LCM of 891,283,961,813,657 with Prime Factorization
| 3 | 891, 283, 961, 813, 657 |
| 3 | 297, 283, 961, 271, 219 |
| 99, 283, 961, 271, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 99 x 283 x 961 x 271 x 73 = 4793797429839
Therefore, the lowest common multiple of 891,283,961,813,657 is 4793797429839.
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.
891 x 283 x 961 x 813 x 657 = 129432530605653
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
283 : 1, 283
961 : 1, 31, 961
813 : 1, 3, 271, 813
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,283,961,813,657, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
283:283
961:31x 31
813:3x 271
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 129432530605653/(1x27)
LCM = 129432530605653/27
LCM = 4793797429839
Thus, we can understand that the LCM of 891,283,961,813,657 is 4793797429839.
