Given numbers are 813,754,171,123,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,754,171,123,123 is 1432585674.
Find LCM of 813,754,171,123,123 with Prime Factorization
| 3 | 813, 754, 171, 123, 123 |
| 41 | 271, 754, 57, 41, 41 |
| 271, 754, 57, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 271 x 754 x 57 x 1 x 1 = 1432585674
Therefore, the lowest common multiple of 813,754,171,123,123 is 1432585674.
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.
813 x 754 x 171 x 123 x 123 = 1585872341118
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.
813 : 1, 3, 271, 813
754 : 1, 2, 13, 26, 29, 58, 377, 754
171 : 1, 3, 9, 19, 57, 171
123 : 1, 3, 41, 123
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,754,171,123,123, is 1.
Now, the common factors can be found like this.
813:3x 271
754:2x 13x 29
171:3x 3x 19
123:3x 41
123:3x 41
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 3x 41 = 1107
Therefore, the value for common factors is 1107.
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 = 1585872341118/(1x1107)
LCM = 1585872341118/1107
LCM = 1432585674
Thus, we can understand that the LCM of 813,754,171,123,123 is 1432585674.
