Given numbers are 382,943,751,442,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,943,751,442,728 is 1674037944488.
Find LCM of 382,943,751,442,728 with Prime Factorization
| 2 | 382, 943, 751, 442, 728 |
| 13 | 191, 943, 751, 221, 364 |
| 191, 943, 751, 17, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 191 x 943 x 751 x 17 x 28 = 1674037944488
Therefore, the lowest common multiple of 382,943,751,442,728 is 1674037944488.
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 943 x 751 x 442 x 728 = 87049973113376
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
943 : 1, 23, 41, 943
751 : 1, 751
442 : 1, 2, 13, 17, 26, 34, 221, 442
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,943,751,442,728, is 1.
Now, the common factors can be found like this.
382:2x 191
943:23x 41
751:751
442:2x 13x 17
728:2x 2x 2x 7x 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 13 = 52
Therefore, the value for common factors is 52.
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 = 87049973113376/(1x52)
LCM = 87049973113376/52
LCM = 1674037944488
Thus, we can understand that the LCM of 382,943,751,442,728 is 1674037944488.
