Given numbers are 171,891,649,110
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,891,649,110 is 9988110.
Find LCM of 171,891,649,110 with Prime Factorization
| 3 | 171, 891, 649, 110 |
| 3 | 57, 297, 649, 110 |
| 11 | 19, 99, 649, 110 |
| 19, 9, 59, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 19 x 9 x 59 x 10 = 9988110
Therefore, the lowest common multiple of 171,891,649,110 is 9988110.
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.
171 x 891 x 649 x 110 = 10877051790
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.
171 : 1, 3, 9, 19, 57, 171
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
649 : 1, 11, 59, 649
110 : 1, 2, 5, 10, 11, 22, 55, 110
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,891,649,110, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
891:3x 3x 3x 3x 11
649:11x 59
110:2x 5x 11
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 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 10877051790/(1x1089)
LCM = 10877051790/1089
LCM = 9988110
Thus, we can understand that the LCM of 171,891,649,110 is 9988110.
