Given numbers are 939,867,763,789,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,867,763,789,609 is 1579216668771.
Find LCM of 939,867,763,789,609 with Prime Factorization
| 3 | 939, 867, 763, 789, 609 |
| 7 | 313, 289, 763, 263, 203 |
| 313, 289, 109, 263, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 313 x 289 x 109 x 263 x 29 = 1579216668771
Therefore, the lowest common multiple of 939,867,763,789,609 is 1579216668771.
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.
939 x 867 x 763 x 789 x 609 = 298471950397719
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.
939 : 1, 3, 313, 939
867 : 1, 3, 17, 51, 289, 867
763 : 1, 7, 109, 763
789 : 1, 3, 263, 789
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,867,763,789,609, is 1.
Now, the common factors can be found like this.
939:3x 313
867:3x 17x 17
763:7x 109
789:3x 263
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 298471950397719/(1x189)
LCM = 298471950397719/189
LCM = 1579216668771
Thus, we can understand that the LCM of 939,867,763,789,609 is 1579216668771.
