The LCM of 848,689,676,943 is 135143216.
Find LCM of 848,689,676,943 with Prime Factorization
| 2 | 848, 689, 676, 943 |
| 2 | 424, 689, 338, 943 |
| 13 | 212, 689, 169, 943 |
| 53 | 212, 53, 13, 943 |
| 4, 1, 13, 943 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 53 x 4 x 1 x 13 x 943 = 135143216
Therefore, the lowest common multiple of 848,689,676,943 is 135143216.
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.
848 x 689 x 676 x 943 = 372454703296
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.
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
689 : 1, 13, 53, 689
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 848,689,676,943, is 1.
Now, the common factors can be found like this.
848:2x 2x 2x 2x 53
689:13x 53
676:2x 2x 13x 13
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.
2x 2x 13x 53 = 2756
Therefore, the value for common factors is 2756.
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 = 372454703296/(1x2756)
LCM = 372454703296/2756
LCM = 135143216
Thus, we can understand that the LCM of 848,689,676,943 is 135143216.
