The LCM of 765,685,731,667,435 is 3005912205.
Find LCM of 765,685,731,667,435 with Prime Factorization
| 3 | 765, 685, 731, 667, 435 |
| 5 | 255, 685, 731, 667, 145 |
| 17 | 51, 137, 731, 667, 29 |
| 29 | 3, 137, 43, 667, 29 |
| 3, 137, 43, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 29 x 3 x 137 x 43 x 23 x 1 = 3005912205
Therefore, the lowest common multiple of 765,685,731,667,435 is 3005912205.
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 685 x 731 x 667 x 435 = 111143603779875
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
685 : 1, 5, 137, 685
731 : 1, 17, 43, 731
667 : 1, 23, 29, 667
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,685,731,667,435, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
685:5x 137
731:17x 43
667:23x 29
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17x 29 = 36975
Therefore, the value for common factors is 36975.
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 = 111143603779875/(1x36975)
LCM = 111143603779875/36975
LCM = 3005912205
Thus, we can understand that the LCM of 765,685,731,667,435 is 3005912205.
