Given numbers are 806,663,378,678,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,663,378,678,554 is 81059511078.
Find LCM of 806,663,378,678,554 with Prime Factorization
| 2 | 806, 663, 378, 678, 554 |
| 3 | 403, 663, 189, 339, 277 |
| 13 | 403, 221, 63, 113, 277 |
| 31, 17, 63, 113, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 17 x 63 x 113 x 277 = 81059511078
Therefore, the lowest common multiple of 806,663,378,678,554 is 81059511078.
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.
806 x 663 x 378 x 678 x 554 = 75871702369008
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
663 : 1, 3, 13, 17, 39, 51, 221, 663
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
678 : 1, 2, 3, 6, 113, 226, 339, 678
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,663,378,678,554, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
663:3x 13x 17
378:2x 3x 3x 3x 7
678:2x 3x 113
554:2x 277
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 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 75871702369008/(1x936)
LCM = 75871702369008/936
LCM = 81059511078
Thus, we can understand that the LCM of 806,663,378,678,554 is 81059511078.
