Given numbers are 685,799,646,959,916
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,799,646,959,916 is 66678291820.
Find LCM of 685,799,646,959,916 with Prime Factorization
| 2 | 685, 799, 646, 959, 916 |
| 17 | 685, 799, 323, 959, 458 |
| 137 | 685, 47, 19, 959, 458 |
| 5, 47, 19, 7, 458 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 137 x 5 x 47 x 19 x 7 x 458 = 66678291820
Therefore, the lowest common multiple of 685,799,646,959,916 is 66678291820.
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.
685 x 799 x 646 x 959 x 916 = 310587483297560
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.
685 : 1, 5, 137, 685
799 : 1, 17, 47, 799
646 : 1, 2, 17, 19, 34, 38, 323, 646
959 : 1, 7, 137, 959
916 : 1, 2, 4, 229, 458, 916
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,799,646,959,916, is 1.
Now, the common factors can be found like this.
685:5x 137
799:17x 47
646:2x 17x 19
959:7x 137
916:2x 2x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 137 = 4658
Therefore, the value for common factors is 4658.
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 = 310587483297560/(1x4658)
LCM = 310587483297560/4658
LCM = 66678291820
Thus, we can understand that the LCM of 685,799,646,959,916 is 66678291820.
