Given numbers are 105,981,629,672,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,981,629,672,892 is 154114158240.
Find LCM of 105,981,629,672,892 with Prime Factorization
| 2 | 105, 981, 629, 672, 892 |
| 2 | 105, 981, 629, 336, 446 |
| 3 | 105, 981, 629, 168, 223 |
| 7 | 35, 327, 629, 56, 223 |
| 5, 327, 629, 8, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 5 x 327 x 629 x 8 x 223 = 154114158240
Therefore, the lowest common multiple of 105,981,629,672,892 is 154114158240.
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.
105 x 981 x 629 x 672 x 892 = 38836767876480
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
981 : 1, 3, 9, 109, 327, 981
629 : 1, 17, 37, 629
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,981,629,672,892, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
981:3x 3x 109
629:17x 37
672:2x 2x 2x 2x 2x 3x 7
892:2x 2x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 38836767876480/(1x252)
LCM = 38836767876480/252
LCM = 154114158240
Thus, we can understand that the LCM of 105,981,629,672,892 is 154114158240.
