Given numbers are 765,806,685,902,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,806,685,902,609 is 7733741004990.
Find LCM of 765,806,685,902,609 with Prime Factorization
| 2 | 765, 806, 685, 902, 609 |
| 3 | 765, 403, 685, 451, 609 |
| 5 | 255, 403, 685, 451, 203 |
| 51, 403, 137, 451, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 51 x 403 x 137 x 451 x 203 = 7733741004990
Therefore, the lowest common multiple of 765,806,685,902,609 is 7733741004990.
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.
765 x 806 x 685 x 902 x 609 = 232012230149700
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
806 : 1, 2, 13, 26, 31, 62, 403, 806
685 : 1, 5, 137, 685
902 : 1, 2, 11, 22, 41, 82, 451, 902
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 765,806,685,902,609, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
806:2x 13x 31
685:5x 137
902:2x 11x 41
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.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 232012230149700/(1x30)
LCM = 232012230149700/30
LCM = 7733741004990
Thus, we can understand that the LCM of 765,806,685,902,609 is 7733741004990.
