Given numbers are 678,622,638,261,366
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,622,638,261,366 is 12309257466.
Find LCM of 678,622,638,261,366 with Prime Factorization
| 2 | 678, 622, 638, 261, 366 |
| 3 | 339, 311, 319, 261, 183 |
| 29 | 113, 311, 319, 87, 61 |
| 113, 311, 11, 3, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 113 x 311 x 11 x 3 x 61 = 12309257466
Therefore, the lowest common multiple of 678,622,638,261,366 is 12309257466.
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.
678 x 622 x 638 x 261 x 366 = 25701729589008
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
622 : 1, 2, 311, 622
638 : 1, 2, 11, 22, 29, 58, 319, 638
261 : 1, 3, 9, 29, 87, 261
366 : 1, 2, 3, 6, 61, 122, 183, 366
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,622,638,261,366, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
622:2x 311
638:2x 11x 29
261:3x 3x 29
366:2x 3x 61
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 29 = 2088
Therefore, the value for common factors is 2088.
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 = 25701729589008/(1x2088)
LCM = 25701729589008/2088
LCM = 12309257466
Thus, we can understand that the LCM of 678,622,638,261,366 is 12309257466.
