Find LCM of 855,198,645,670,885 with Prime Factorization
| 2 | 855, 198, 645, 670, 885 |
| 3 | 855, 99, 645, 335, 885 |
| 3 | 285, 33, 215, 335, 295 |
| 5 | 95, 11, 215, 335, 295 |
| 19, 11, 43, 67, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 19 x 11 x 43 x 67 x 59 = 3197304990
Therefore, the lowest common multiple of 855,198,645,670,885 is 3197304990.
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.
855 x 198 x 645 x 670 x 885 = 64745426047500
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
645 : 1, 3, 5, 15, 43, 129, 215, 645
670 : 1, 2, 5, 10, 67, 134, 335, 670
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,198,645,670,885, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
198:2x 3x 3x 11
645:3x 5x 43
670:2x 5x 67
885:3x 5x 59
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 3x 3x 3x 5x 5x 5 = 20250
Therefore, the value for common factors is 20250.
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 = 64745426047500/(1x20250)
LCM = 64745426047500/20250
LCM = 3197304990
Thus, we can understand that the LCM of 855,198,645,670,885 is 3197304990.
