Given numbers are 206,721,646,119
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 206,721,646,119 is 465766.
Find LCM of 206,721,646,119 with Prime Factorization
| 2 | 206, 721, 646, 119 |
| 7 | 103, 721, 323, 119 |
| 17 | 103, 103, 323, 17 |
| 103 | 103, 103, 19, 1 |
| 1, 1, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 103 x 1 x 1 x 19 x 1 = 465766
Therefore, the lowest common multiple of 206,721,646,119 is 465766.
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.
206 x 721 x 646 x 119 = 11417787724
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.
206 : 1, 2, 103, 206
721 : 1, 7, 103, 721
646 : 1, 2, 17, 19, 34, 38, 323, 646
119 : 1, 7, 17, 119
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,721,646,119, is 1.
Now, the common factors can be found like this.
206:2x 103
721:7x 103
646:2x 17x 19
119:7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 17x 103 = 24514
Therefore, the value for common factors is 24514.
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 = 11417787724/(1x24514)
LCM = 11417787724/24514
LCM = 465766
Thus, we can understand that the LCM of 206,721,646,119 is 465766.
