Given numbers are 289,754,858,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,754,858,406 is 50336286.
Find LCM of 289,754,858,406 with Prime Factorization
| 2 | 289, 754, 858, 406 |
| 13 | 289, 377, 429, 203 |
| 29 | 289, 29, 33, 203 |
| 289, 1, 33, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 289 x 1 x 33 x 7 = 50336286
Therefore, the lowest common multiple of 289,754,858,406 is 50336286.
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.
289 x 754 x 858 x 406 = 75907119288
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.
289 : 1, 17, 289
754 : 1, 2, 13, 26, 29, 58, 377, 754
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,754,858,406, is 1.
Now, the common factors can be found like this.
289:17x 17
754:2x 13x 29
858:2x 3x 11x 13
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 13x 29 = 1508
Therefore, the value for common factors is 1508.
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 = 75907119288/(1x1508)
LCM = 75907119288/1508
LCM = 50336286
Thus, we can understand that the LCM of 289,754,858,406 is 50336286.
