Given numbers are 191,916,458,655,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,916,458,655,161 is 18449984980.
Find LCM of 191,916,458,655,161 with Prime Factorization
| 2 | 191, 916, 458, 655, 161 |
| 229 | 191, 458, 229, 655, 161 |
| 191, 2, 1, 655, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 229 x 191 x 2 x 1 x 655 x 161 = 18449984980
Therefore, the lowest common multiple of 191,916,458,655,161 is 18449984980.
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.
191 x 916 x 458 x 655 x 161 = 8450093120840
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.
191 : 1, 191
916 : 1, 2, 4, 229, 458, 916
458 : 1, 2, 229, 458
655 : 1, 5, 131, 655
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,916,458,655,161, is 1.
Now, the common factors can be found like this.
191:191
916:2x 2x 229
458:2x 229
655:5x 131
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 229 = 458
Therefore, the value for common factors is 458.
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 = 8450093120840/(1x458)
LCM = 8450093120840/458
LCM = 18449984980
Thus, we can understand that the LCM of 191,916,458,655,161 is 18449984980.
