Given numbers are 809,640,851,629,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,640,851,629,388 is 726572090240.
Find LCM of 809,640,851,629,388 with Prime Factorization
| 2 | 809, 640, 851, 629, 388 |
| 2 | 809, 320, 851, 629, 194 |
| 37 | 809, 160, 851, 629, 97 |
| 809, 160, 23, 17, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 809 x 160 x 23 x 17 x 97 = 726572090240
Therefore, the lowest common multiple of 809,640,851,629,388 is 726572090240.
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.
809 x 640 x 851 x 629 x 388 = 107532669355520
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.
809 : 1, 809
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
851 : 1, 23, 37, 851
629 : 1, 17, 37, 629
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,640,851,629,388, is 1.
Now, the common factors can be found like this.
809:809
640:2x 2x 2x 2x 2x 2x 2x 5
851:23x 37
629:17x 37
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 37 = 148
Therefore, the value for common factors is 148.
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 = 107532669355520/(1x148)
LCM = 107532669355520/148
LCM = 726572090240
Thus, we can understand that the LCM of 809,640,851,629,388 is 726572090240.
