Given numbers are 999,997,741,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,997,741,161 is 39608051301.
Find LCM of 999,997,741,161 with Prime Factorization
| 3 | 999, 997, 741, 161 |
| 333, 997, 247, 161 |
Multiply the prime numbers at the bottom and the left side.
3 x 333 x 997 x 247 x 161 = 39608051301
Therefore, the lowest common multiple of 999,997,741,161 is 39608051301.
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.
999 x 997 x 741 x 161 = 118824153903
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
997 : 1, 997
741 : 1, 3, 13, 19, 39, 57, 247, 741
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,997,741,161, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
997:997
741:3x 13x 19
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 118824153903/(1x3)
LCM = 118824153903/3
LCM = 39608051301
Thus, we can understand that the LCM of 999,997,741,161 is 39608051301.
