Given numbers are 742,682,209,644,206
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,682,209,644,206 is 22777546484.
Find LCM of 742,682,209,644,206 with Prime Factorization
| 2 | 742, 682, 209, 644, 206 |
| 7 | 371, 341, 209, 322, 103 |
| 11 | 53, 341, 209, 46, 103 |
| 53, 31, 19, 46, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 53 x 31 x 19 x 46 x 103 = 22777546484
Therefore, the lowest common multiple of 742,682,209,644,206 is 22777546484.
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.
742 x 682 x 209 x 644 x 206 = 14030968634144
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
682 : 1, 2, 11, 22, 31, 62, 341, 682
209 : 1, 11, 19, 209
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
206 : 1, 2, 103, 206
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,682,209,644,206, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
682:2x 11x 31
209:11x 19
644:2x 2x 7x 23
206:2x 103
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 2x 7x 11 = 616
Therefore, the value for common factors is 616.
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 = 14030968634144/(1x616)
LCM = 14030968634144/616
LCM = 22777546484
Thus, we can understand that the LCM of 742,682,209,644,206 is 22777546484.
