Given numbers are 393,786,917,547
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,786,917,547 is 3009594.
Find LCM of 393,786,917,547 with Prime Factorization
| 3 | 393, 786, 917, 547 |
| 131 | 131, 262, 917, 547 |
| 1, 2, 7, 547 |
Multiply the prime numbers at the bottom and the left side.
3 x 131 x 1 x 2 x 7 x 547 = 3009594
Therefore, the lowest common multiple of 393,786,917,547 is 3009594.
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.
393 x 786 x 917 x 547 = 154942927902
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.
393 : 1, 3, 131, 393
786 : 1, 2, 3, 6, 131, 262, 393, 786
917 : 1, 7, 131, 917
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,786,917,547, is 1.
Now, the common factors can be found like this.
393:3x 131
786:2x 3x 131
917:7x 131
547:547
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 131x 131 = 51483
Therefore, the value for common factors is 51483.
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 = 154942927902/(1x51483)
LCM = 154942927902/51483
LCM = 3009594
Thus, we can understand that the LCM of 393,786,917,547 is 3009594.
