Find LCM of 871,765,806,790,939 with Prime Factorization
| 2 | 871, 765, 806, 790, 939 |
| 3 | 871, 765, 403, 395, 939 |
| 5 | 871, 255, 403, 395, 313 |
| 13 | 871, 51, 403, 79, 313 |
| 67, 51, 31, 79, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 67 x 51 x 31 x 79 x 313 = 1021510202310
Therefore, the lowest common multiple of 871,765,806,790,939 is 1021510202310.
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.
871 x 765 x 806 x 790 x 939 = 398388978900900
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.
871 : 1, 13, 67, 871
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
806 : 1, 2, 13, 26, 31, 62, 403, 806
790 : 1, 2, 5, 10, 79, 158, 395, 790
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,765,806,790,939, is 1.
Now, the common factors can be found like this.
871:13x 67
765:3x 3x 5x 17
806:2x 13x 31
790:2x 5x 79
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 398388978900900/(1x390)
LCM = 398388978900900/390
LCM = 1021510202310
Thus, we can understand that the LCM of 871,765,806,790,939 is 1021510202310.
