Given numbers are 981,923,605,429,206
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,923,605,429,206 is 112847853690.
Find LCM of 981,923,605,429,206 with Prime Factorization
| 3 | 981, 923, 605, 429, 206 |
| 11 | 327, 923, 605, 143, 206 |
| 13 | 327, 923, 55, 13, 206 |
| 327, 71, 55, 1, 206 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 13 x 327 x 71 x 55 x 1 x 206 = 112847853690
Therefore, the lowest common multiple of 981,923,605,429,206 is 112847853690.
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.
981 x 923 x 605 x 429 x 206 = 48411729233010
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.
981 : 1, 3, 9, 109, 327, 981
923 : 1, 13, 71, 923
605 : 1, 5, 11, 55, 121, 605
429 : 1, 3, 11, 13, 33, 39, 143, 429
206 : 1, 2, 103, 206
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,923,605,429,206, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
923:13x 71
605:5x 11x 11
429:3x 11x 13
206:2x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 13 = 429
Therefore, the value for common factors is 429.
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 = 48411729233010/(1x429)
LCM = 48411729233010/429
LCM = 112847853690
Thus, we can understand that the LCM of 981,923,605,429,206 is 112847853690.
