Given numbers are 605,381,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,381,381 is 230505.
Find LCM of 605,381,381 with Prime Factorization
3 | 605, 381, 381 |
127 | 605, 127, 127 |
605, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 605 x 1 x 1 = 230505
Therefore, the lowest common multiple of 605,381,381 is 230505.
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.
605 x 381 x 381 = 87822405
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.
605 : 1, 5, 11, 55, 121, 605
381 : 1, 3, 127, 381
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,381,381, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
381:3x 127
381:3x 127
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 = 87822405/(1x381)
LCM = 87822405/381
LCM = 230505
Thus, we can understand that the LCM of 605,381,381 is 230505.
