Given numbers are 939,385,660,789,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 939,385,660,789,685 is 52102987860.
Find LCM of 939,385,660,789,685 with Prime Factorization
| 3 | 939, 385, 660, 789, 685 |
| 5 | 313, 385, 220, 263, 685 |
| 11 | 313, 77, 44, 263, 137 |
| 313, 7, 4, 263, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 313 x 7 x 4 x 263 x 137 = 52102987860
Therefore, the lowest common multiple of 939,385,660,789,685 is 52102987860.
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 385 x 660 x 789 x 685 = 128954894953500
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
385 : 1, 5, 7, 11, 35, 55, 77, 385
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
789 : 1, 3, 263, 789
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 939,385,660,789,685, is 1.
Now, the common factors can be found like this.
939:3x 313
385:5x 7x 11
660:2x 2x 3x 5x 11
789:3x 263
685:5x 137
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 5x 5x 11 = 2475
Therefore, the value for common factors is 2475.
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 = 128954894953500/(1x2475)
LCM = 128954894953500/2475
LCM = 52102987860
Thus, we can understand that the LCM of 939,385,660,789,685 is 52102987860.
