Given numbers are 845,834,834,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,834,834,678 is 79634490.
Find LCM of 845,834,834,678 with Prime Factorization
| 2 | 845, 834, 834, 678 |
| 3 | 845, 417, 417, 339 |
| 139 | 845, 139, 139, 113 |
| 845, 1, 1, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 139 x 845 x 1 x 1 x 113 = 79634490
Therefore, the lowest common multiple of 845,834,834,678 is 79634490.
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.
845 x 834 x 834 x 678 = 398490987960
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.
845 : 1, 5, 13, 65, 169, 845
834 : 1, 2, 3, 6, 139, 278, 417, 834
834 : 1, 2, 3, 6, 139, 278, 417, 834
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,834,834,678, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
834:2x 3x 139
834:2x 3x 139
678:2x 3x 113
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 139 = 5004
Therefore, the value for common factors is 5004.
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 = 398490987960/(1x5004)
LCM = 398490987960/5004
LCM = 79634490
Thus, we can understand that the LCM of 845,834,834,678 is 79634490.
