Given numbers are 786,124,315,394,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,124,315,394,486 is 27216578340.
Find LCM of 786,124,315,394,486 with Prime Factorization
| 2 | 786, 124, 315, 394, 486 |
| 3 | 393, 62, 315, 197, 243 |
| 3 | 131, 62, 105, 197, 81 |
| 131, 62, 35, 197, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 131 x 62 x 35 x 197 x 27 = 27216578340
Therefore, the lowest common multiple of 786,124,315,394,486 is 27216578340.
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.
786 x 124 x 315 x 394 x 486 = 5878780921440
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
124 : 1, 2, 4, 31, 62, 124
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
394 : 1, 2, 197, 394
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,124,315,394,486, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
124:2x 2x 31
315:3x 3x 5x 7
394:2x 197
486:2x 3x 3x 3x 3x 3
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 3 = 216
Therefore, the value for common factors is 216.
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 = 5878780921440/(1x216)
LCM = 5878780921440/216
LCM = 27216578340
Thus, we can understand that the LCM of 786,124,315,394,486 is 27216578340.
