Given numbers are 209,627,608,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,627,608,861 is 5758368.
Find LCM of 209,627,608,861 with Prime Factorization
| 3 | 209, 627, 608, 861 |
| 11 | 209, 209, 608, 287 |
| 19 | 19, 19, 608, 287 |
| 1, 1, 32, 287 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 1 x 1 x 32 x 287 = 5758368
Therefore, the lowest common multiple of 209,627,608,861 is 5758368.
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.
209 x 627 x 608 x 861 = 68599437984
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.
209 : 1, 11, 19, 209
627 : 1, 3, 11, 19, 33, 57, 209, 627
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,627,608,861, is 1.
Now, the common factors can be found like this.
209:11x 19
627:3x 11x 19
608:2x 2x 2x 2x 2x 19
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 19x 19 = 11913
Therefore, the value for common factors is 11913.
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 = 68599437984/(1x11913)
LCM = 68599437984/11913
LCM = 5758368
Thus, we can understand that the LCM of 209,627,608,861 is 5758368.
