| 13 | 689, 81, 1, 401, 13 |
| 53, 81, 1, 401, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 11 x 13 x 53 x 81 x 1 x 401 x 1 = 7877551968
Therefore, the lowest common multiple of 689,891,352,802,416 is 7877551968.
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 891 x 352 x 802 x 416 = 72095355611136
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
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
802 : 1, 2, 401, 802
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,891,352,802,416, is 1.
Now, the common factors can be found like this.
689:13x 53
891:3x 3x 3x 3x 11
352:2x 2x 2x 2x 2x 11
802:2x 401
416:2x 2x 2x 2x 2x 13
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 2x 2x 2x 11x 13 = 9152
Therefore, the value for common factors is 9152.
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 = 72095355611136/(1x9152)
LCM = 72095355611136/9152
LCM = 7877551968
Thus, we can understand that the LCM of 689,891,352,802,416 is 7877551968.
