Given numbers are 685,170,986,366
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,170,986,366 is 123600030.
Find LCM of 685,170,986,366 with Prime Factorization
| 2 | 685, 170, 986, 366 |
| 5 | 685, 85, 493, 183 |
| 17 | 137, 17, 493, 183 |
| 137, 1, 29, 183 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 137 x 1 x 29 x 183 = 123600030
Therefore, the lowest common multiple of 685,170,986,366 is 123600030.
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 170 x 986 x 366 = 42024010200
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
986 : 1, 2, 17, 29, 34, 58, 493, 986
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 685,170,986,366, is 1.
Now, the common factors can be found like this.
685:5x 137
170:2x 5x 17
986:2x 17x 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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 42024010200/(1x340)
LCM = 42024010200/340
LCM = 123600030
Thus, we can understand that the LCM of 685,170,986,366 is 123600030.
