Given numbers are 381,762,187,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,762,187,105 is 4987290.
Find LCM of 381,762,187,105 with Prime Factorization
| 3 | 381, 762, 187, 105 |
| 127 | 127, 254, 187, 35 |
| 1, 2, 187, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 1 x 2 x 187 x 35 = 4987290
Therefore, the lowest common multiple of 381,762,187,105 is 4987290.
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 762 x 187 x 105 = 5700472470
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
762 : 1, 2, 3, 6, 127, 254, 381, 762
187 : 1, 11, 17, 187
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,762,187,105, is 1.
Now, the common factors can be found like this.
381:3x 127
762:2x 3x 127
187:11x 17
105:3x 5x 7
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 127 = 1143
Therefore, the value for common factors is 1143.
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 = 5700472470/(1x1143)
LCM = 5700472470/1143
LCM = 4987290
Thus, we can understand that the LCM of 381,762,187,105 is 4987290.
