Given numbers are 165,905,988,397,158
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,905,988,397,158 is 925416123060.
Find LCM of 165,905,988,397,158 with Prime Factorization
| 2 | 165, 905, 988, 397, 158 |
| 5 | 165, 905, 494, 397, 79 |
| 33, 181, 494, 397, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 33 x 181 x 494 x 397 x 79 = 925416123060
Therefore, the lowest common multiple of 165,905,988,397,158 is 925416123060.
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.
165 x 905 x 988 x 397 x 158 = 9254161230600
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
905 : 1, 5, 181, 905
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
397 : 1, 397
158 : 1, 2, 79, 158
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,905,988,397,158, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
905:5x 181
988:2x 2x 13x 19
397:397
158:2x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 9254161230600/(1x10)
LCM = 9254161230600/10
LCM = 925416123060
Thus, we can understand that the LCM of 165,905,988,397,158 is 925416123060.
