Find LCM of 646,813,766,798,329 with Prime Factorization
| 2 | 646, 813, 766, 798, 329 |
| 3 | 323, 813, 383, 399, 329 |
| 7 | 323, 271, 383, 133, 329 |
| 19 | 323, 271, 383, 19, 47 |
| 17, 271, 383, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 17 x 271 x 383 x 1 x 47 = 66178624386
Therefore, the lowest common multiple of 646,813,766,798,329 is 66178624386.
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.
646 x 813 x 766 x 798 x 329 = 105621084520056
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
813 : 1, 3, 271, 813
766 : 1, 2, 383, 766
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,813,766,798,329, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
813:3x 271
766:2x 383
798:2x 3x 7x 19
329:7x 47
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 3x 7x 19 = 1596
Therefore, the value for common factors is 1596.
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 = 105621084520056/(1x1596)
LCM = 105621084520056/1596
LCM = 66178624386
Thus, we can understand that the LCM of 646,813,766,798,329 is 66178624386.
