Find LCM of 649,514,685,891,621 with Prime Factorization
| 3 | 649, 514, 685, 891, 621 |
| 3 | 649, 514, 685, 297, 207 |
| 3 | 649, 514, 685, 99, 69 |
| 11 | 649, 514, 685, 33, 23 |
| 59, 514, 685, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 11 x 59 x 514 x 685 x 3 x 23 = 425707441830
Therefore, the lowest common multiple of 649,514,685,891,621 is 425707441830.
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.
649 x 514 x 685 x 891 x 621 = 126435110223510
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.
649 : 1, 11, 59, 649
514 : 1, 2, 257, 514
685 : 1, 5, 137, 685
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,514,685,891,621, is 1.
Now, the common factors can be found like this.
649:11x 59
514:2x 257
685:5x 137
891:3x 3x 3x 3x 11
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 126435110223510/(1x297)
LCM = 126435110223510/297
LCM = 425707441830
Thus, we can understand that the LCM of 649,514,685,891,621 is 425707441830.
