Given numbers are 381,209,806,381,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,209,806,381,793 is 3915039414.
Find LCM of 381,209,806,381,793 with Prime Factorization
3 | 381, 209, 806, 381, 793 |
13 | 127, 209, 806, 127, 793 |
127 | 127, 209, 62, 127, 61 |
1, 209, 62, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 127 x 1 x 209 x 62 x 1 x 61 = 3915039414
Therefore, the lowest common multiple of 381,209,806,381,793 is 3915039414.
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 209 x 806 x 381 x 793 = 19391190217542
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
209 : 1, 11, 19, 209
806 : 1, 2, 13, 26, 31, 62, 403, 806
381 : 1, 3, 127, 381
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,209,806,381,793, is 1.
Now, the common factors can be found like this.
381:3x 127
209:11x 19
806:2x 13x 31
381:3x 127
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 127 = 4953
Therefore, the value for common factors is 4953.
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 = 19391190217542/(1x4953)
LCM = 19391190217542/4953
LCM = 3915039414
Thus, we can understand that the LCM of 381,209,806,381,793 is 3915039414.
