Find LCM of 689,247,848,808,687 with Prime Factorization
| 2 | 689, 247, 848, 808, 687 |
| 2 | 689, 247, 424, 404, 687 |
| 2 | 689, 247, 212, 202, 687 |
| 13 | 689, 247, 106, 101, 687 |
| 53 | 53, 19, 106, 101, 687 |
| 1, 19, 2, 101, 687 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 53 x 1 x 19 x 2 x 101 x 687 = 14533523472
Therefore, the lowest common multiple of 689,247,848,808,687 is 14533523472.
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.
689 x 247 x 848 x 808 x 687 = 80108781377664
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.
689 : 1, 13, 53, 689
247 : 1, 13, 19, 247
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
808 : 1, 2, 4, 8, 101, 202, 404, 808
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,247,848,808,687, is 1.
Now, the common factors can be found like this.
689:13x 53
247:13x 19
848:2x 2x 2x 2x 53
808:2x 2x 2x 101
687:3x 229
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 13x 53 = 5512
Therefore, the value for common factors is 5512.
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 = 80108781377664/(1x5512)
LCM = 80108781377664/5512
LCM = 14533523472
Thus, we can understand that the LCM of 689,247,848,808,687 is 14533523472.
