Given numbers are 382,645,511,317,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,645,511,317,640 is 2554366523520.
Find LCM of 382,645,511,317,640 with Prime Factorization
| 2 | 382, 645, 511, 317, 640 |
| 5 | 191, 645, 511, 317, 320 |
| 191, 129, 511, 317, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 191 x 129 x 511 x 317 x 64 = 2554366523520
Therefore, the lowest common multiple of 382,645,511,317,640 is 2554366523520.
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.
382 x 645 x 511 x 317 x 640 = 25543665235200
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.
382 : 1, 2, 191, 382
645 : 1, 3, 5, 15, 43, 129, 215, 645
511 : 1, 7, 73, 511
317 : 1, 317
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,645,511,317,640, is 1.
Now, the common factors can be found like this.
382:2x 191
645:3x 5x 43
511:7x 73
317:317
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 25543665235200/(1x10)
LCM = 25543665235200/10
LCM = 2554366523520
Thus, we can understand that the LCM of 382,645,511,317,640 is 2554366523520.
