Given numbers are 378,644,998,434,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,644,998,434,843 is 75581967132.
Find LCM of 378,644,998,434,843 with Prime Factorization
| 2 | 378, 644, 998, 434, 843 |
| 3 | 189, 322, 499, 217, 843 |
| 7 | 63, 322, 499, 217, 281 |
| 9, 46, 499, 31, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 9 x 46 x 499 x 31 x 281 = 75581967132
Therefore, the lowest common multiple of 378,644,998,434,843 is 75581967132.
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.
378 x 644 x 998 x 434 x 843 = 88884393347232
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
998 : 1, 2, 499, 998
434 : 1, 2, 7, 14, 31, 62, 217, 434
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,644,998,434,843, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
644:2x 2x 7x 23
998:2x 499
434:2x 7x 31
843:3x 281
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 7 = 1176
Therefore, the value for common factors is 1176.
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 = 88884393347232/(1x1176)
LCM = 88884393347232/1176
LCM = 75581967132
Thus, we can understand that the LCM of 378,644,998,434,843 is 75581967132.
