Given numbers are 789,794,810,397,208
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,794,810,397,208 is 8795582640.
Find LCM of 789,794,810,397,208 with Prime Factorization
| 2 | 789, 794, 810, 397, 208 |
| 3 | 789, 397, 405, 397, 104 |
| 397 | 263, 397, 135, 397, 104 |
| 263, 1, 135, 1, 104 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 397 x 263 x 1 x 135 x 1 x 104 = 8795582640
Therefore, the lowest common multiple of 789,794,810,397,208 is 8795582640.
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.
789 x 794 x 810 x 397 x 208 = 41902155696960
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.
789 : 1, 3, 263, 789
794 : 1, 2, 397, 794
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
397 : 1, 397
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,794,810,397,208, is 1.
Now, the common factors can be found like this.
789:3x 263
794:2x 397
810:2x 3x 3x 3x 3x 5
397:397
208:2x 2x 2x 2x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 397 = 4764
Therefore, the value for common factors is 4764.
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 = 41902155696960/(1x4764)
LCM = 41902155696960/4764
LCM = 8795582640
Thus, we can understand that the LCM of 789,794,810,397,208 is 8795582640.
