Given numbers are 207,981,981,344
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,981,981,344 is 7761672.
Find LCM of 207,981,981,344 with Prime Factorization
| 3 | 207, 981, 981, 344 |
| 3 | 69, 327, 327, 344 |
| 109 | 23, 109, 109, 344 |
| 23, 1, 1, 344 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 109 x 23 x 1 x 1 x 344 = 7761672
Therefore, the lowest common multiple of 207,981,981,344 is 7761672.
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.
207 x 981 x 981 x 344 = 68527802088
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.
207 : 1, 3, 9, 23, 69, 207
981 : 1, 3, 9, 109, 327, 981
981 : 1, 3, 9, 109, 327, 981
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,981,981,344, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
981:3x 3x 109
981:3x 3x 109
344:2x 2x 2x 43
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 3x 3x 109 = 8829
Therefore, the value for common factors is 8829.
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 = 68527802088/(1x8829)
LCM = 68527802088/8829
LCM = 7761672
Thus, we can understand that the LCM of 207,981,981,344 is 7761672.
