Given numbers are 158,687,771,360,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 158,687,771,360,289 is 483722223480.
Find LCM of 158,687,771,360,289 with Prime Factorization
| 2 | 158, 687, 771, 360, 289 |
| 3 | 79, 687, 771, 180, 289 |
| 79, 229, 257, 60, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 79 x 229 x 257 x 60 x 289 = 483722223480
Therefore, the lowest common multiple of 158,687,771,360,289 is 483722223480.
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.
158 x 687 x 771 x 360 x 289 = 8707000022640
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.
158 : 1, 2, 79, 158
687 : 1, 3, 229, 687
771 : 1, 3, 257, 771
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,687,771,360,289, is 1.
Now, the common factors can be found like this.
158:2x 79
687:3x 229
771:3x 257
360:2x 2x 2x 3x 3x 5
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 8707000022640/(1x18)
LCM = 8707000022640/18
LCM = 483722223480
Thus, we can understand that the LCM of 158,687,771,360,289 is 483722223480.
