The LCM of 689,658,546,384,818 is 35601611136.
Find LCM of 689,658,546,384,818 with Prime Factorization
| 2 | 689, 658, 546, 384, 818 |
| 3 | 689, 329, 273, 192, 409 |
| 7 | 689, 329, 91, 64, 409 |
| 13 | 689, 47, 13, 64, 409 |
| 53, 47, 1, 64, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 53 x 47 x 1 x 64 x 409 = 35601611136
Therefore, the lowest common multiple of 689,658,546,384,818 is 35601611136.
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 658 x 546 x 384 x 818 = 77753918721024
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
658 : 1, 2, 7, 14, 47, 94, 329, 658
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,658,546,384,818, is 1.
Now, the common factors can be found like this.
689:13x 53
658:2x 7x 47
546:2x 3x 7x 13
384:2x 2x 2x 2x 2x 2x 2x 3
818:2x 409
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 3x 7x 13 = 2184
Therefore, the value for common factors is 2184.
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 = 77753918721024/(1x2184)
LCM = 77753918721024/2184
LCM = 35601611136
Thus, we can understand that the LCM of 689,658,546,384,818 is 35601611136.
