Find LCM of 808,516,488,855,989 with Prime Factorization
| 2 | 808, 516, 488, 855, 989 |
| 2 | 404, 258, 244, 855, 989 |
| 2 | 202, 129, 122, 855, 989 |
| 3 | 101, 129, 61, 855, 989 |
| 43 | 101, 43, 61, 285, 989 |
| 101, 1, 61, 285, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 43 x 101 x 1 x 61 x 285 x 23 = 41677686360
Therefore, the lowest common multiple of 808,516,488,855,989 is 41677686360.
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.
808 x 516 x 488 x 855 x 989 = 172045489294080
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
488 : 1, 2, 4, 8, 61, 122, 244, 488
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,516,488,855,989, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
516:2x 2x 3x 43
488:2x 2x 2x 61
855:3x 3x 5x 19
989:23x 43
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 2x 2x 2x 3x 43 = 4128
Therefore, the value for common factors is 4128.
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 = 172045489294080/(1x4128)
LCM = 172045489294080/4128
LCM = 41677686360
Thus, we can understand that the LCM of 808,516,488,855,989 is 41677686360.
