The LCM of 891,668,675,943 is 14031557100.
Find LCM of 891,668,675,943 with Prime Factorization
| 3 | 891, 668, 675, 943 |
| 3 | 297, 668, 225, 943 |
| 3 | 99, 668, 75, 943 |
| 33, 668, 25, 943 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 33 x 668 x 25 x 943 = 14031557100
Therefore, the lowest common multiple of 891,668,675,943 is 14031557100.
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.
891 x 668 x 675 x 943 = 378852041700
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
668 : 1, 2, 4, 167, 334, 668
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,668,675,943, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
668:2x 2x 167
675:3x 3x 3x 5x 5
943:23x 41
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 3 = 27
Therefore, the value for common factors is 27.
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 = 378852041700/(1x27)
LCM = 378852041700/27
LCM = 14031557100
Thus, we can understand that the LCM of 891,668,675,943 is 14031557100.
