The LCM of 671,999,765,891 is 170933895.
Find LCM of 671,999,765,891 with Prime Factorization
| 3 | 671, 999, 765, 891 |
| 3 | 671, 333, 255, 297 |
| 3 | 671, 111, 85, 99 |
| 11 | 671, 37, 85, 33 |
| 61, 37, 85, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 11 x 61 x 37 x 85 x 3 = 170933895
Therefore, the lowest common multiple of 671,999,765,891 is 170933895.
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.
671 x 999 x 765 x 891 = 456906301335
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.
671 : 1, 11, 61, 671
999 : 1, 3, 9, 27, 37, 111, 333, 999
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,999,765,891, is 1.
Now, the common factors can be found like this.
671:11x 61
999:3x 3x 3x 37
765:3x 3x 5x 17
891:3x 3x 3x 3x 11
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 3x 3x 11 = 2673
Therefore, the value for common factors is 2673.
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 = 456906301335/(1x2673)
LCM = 456906301335/2673
LCM = 170933895
Thus, we can understand that the LCM of 671,999,765,891 is 170933895.
