Given numbers are 381,206,271,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,206,271,542 is 21269706.
Find LCM of 381,206,271,542 with Prime Factorization
| 2 | 381, 206, 271, 542 |
| 271 | 381, 103, 271, 271 |
| 381, 103, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 271 x 381 x 103 x 1 x 1 = 21269706
Therefore, the lowest common multiple of 381,206,271,542 is 21269706.
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 206 x 271 x 542 = 11528180652
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
206 : 1, 2, 103, 206
271 : 1, 271
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,206,271,542, is 1.
Now, the common factors can be found like this.
381:3x 127
206:2x 103
271:271
542:2x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 271 = 542
Therefore, the value for common factors is 542.
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 = 11528180652/(1x542)
LCM = 11528180652/542
LCM = 21269706
Thus, we can understand that the LCM of 381,206,271,542 is 21269706.
