Given numbers are 726,418,105,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,418,105,389 is 187805310.
Find LCM of 726,418,105,389 with Prime Factorization
| 2 | 726, 418, 105, 389 |
| 3 | 363, 209, 105, 389 |
| 11 | 121, 209, 35, 389 |
| 11, 19, 35, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 11 x 19 x 35 x 389 = 187805310
Therefore, the lowest common multiple of 726,418,105,389 is 187805310.
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.
726 x 418 x 105 x 389 = 12395150460
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
418 : 1, 2, 11, 19, 22, 38, 209, 418
105 : 1, 3, 5, 7, 15, 21, 35, 105
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,418,105,389, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
418:2x 11x 19
105:3x 5x 7
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.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 12395150460/(1x66)
LCM = 12395150460/66
LCM = 187805310
Thus, we can understand that the LCM of 726,418,105,389 is 187805310.
