Given numbers are 381,378,859,798,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,378,859,798,786 is 102639276306.
Find LCM of 381,378,859,798,786 with Prime Factorization
| 2 | 381, 378, 859, 798, 786 |
| 3 | 381, 189, 859, 399, 393 |
| 7 | 127, 63, 859, 133, 131 |
| 127, 9, 859, 19, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 127 x 9 x 859 x 19 x 131 = 102639276306
Therefore, the lowest common multiple of 381,378,859,798,786 is 102639276306.
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.
381 x 378 x 859 x 798 x 786 = 77595292887336
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.
381 : 1, 3, 127, 381
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
859 : 1, 859
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,378,859,798,786, is 1.
Now, the common factors can be found like this.
381:3x 127
378:2x 3x 3x 3x 7
859:859
798:2x 3x 7x 19
786:2x 3x 131
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 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 77595292887336/(1x756)
LCM = 77595292887336/756
LCM = 102639276306
Thus, we can understand that the LCM of 381,378,859,798,786 is 102639276306.
