Find LCM of 806,770,385,839,309 with Prime Factorization
| 2 | 806, 770, 385, 839, 309 |
| 5 | 403, 385, 385, 839, 309 |
| 7 | 403, 77, 77, 839, 309 |
| 11 | 403, 11, 11, 839, 309 |
| 403, 1, 1, 839, 309 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 403 x 1 x 1 x 839 x 309 = 80448177810
Therefore, the lowest common multiple of 806,770,385,839,309 is 80448177810.
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.
806 x 770 x 385 x 839 x 309 = 61945096913700
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
385 : 1, 5, 7, 11, 35, 55, 77, 385
839 : 1, 839
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,770,385,839,309, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
770:2x 5x 7x 11
385:5x 7x 11
839:839
309:3x 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 5x 7x 11 = 770
Therefore, the value for common factors is 770.
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 = 61945096913700/(1x770)
LCM = 61945096913700/770
LCM = 80448177810
Thus, we can understand that the LCM of 806,770,385,839,309 is 80448177810.
