Given numbers are 644,313,934,388,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,313,934,388,378 is 246537270756.
Find LCM of 644,313,934,388,378 with Prime Factorization
| 2 | 644, 313, 934, 388, 378 |
| 2 | 322, 313, 467, 194, 189 |
| 7 | 161, 313, 467, 97, 189 |
| 23, 313, 467, 97, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 313 x 467 x 97 x 27 = 246537270756
Therefore, the lowest common multiple of 644,313,934,388,378 is 246537270756.
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.
644 x 313 x 934 x 388 x 378 = 27612174324672
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
313 : 1, 313
934 : 1, 2, 467, 934
388 : 1, 2, 4, 97, 194, 388
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,313,934,388,378, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
313:313
934:2x 467
388:2x 2x 97
378:2x 3x 3x 3x 7
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 27612174324672/(1x112)
LCM = 27612174324672/112
LCM = 246537270756
Thus, we can understand that the LCM of 644,313,934,388,378 is 246537270756.
