Given numbers are 381,508,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,508,261 is 132588.
Find LCM of 381,508,261 with Prime Factorization
| 3 | 381, 508, 261 |
| 127 | 127, 508, 87 |
| 1, 4, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 1 x 4 x 87 = 132588
Therefore, the lowest common multiple of 381,508,261 is 132588.
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.
381 x 508 x 261 = 50516028
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.
381 : 1, 3, 127, 381
508 : 1, 2, 4, 127, 254, 508
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,508,261, is 1.
Now, the common factors can be found like this.
381:3x 127
508:2x 2x 127
261:3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 127 = 381
Therefore, the value for common factors is 381.
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 = 50516028/(1x381)
LCM = 50516028/381
LCM = 132588
Thus, we can understand that the LCM of 381,508,261 is 132588.
