The LCM of 170,782,196,805 is 383180.
Find LCM of 170,782,196,805 with Prime Factorization
| 2 | 170, 782, 196, 805 |
| 5 | 85, 391, 98, 805 |
| 7 | 17, 391, 98, 161 |
| 17 | 17, 391, 14, 23 |
| 23 | 1, 23, 14, 23 |
| 1, 1, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 17 x 23 x 1 x 1 x 14 x 1 = 383180
Therefore, the lowest common multiple of 170,782,196,805 is 383180.
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.
170 x 782 x 196 x 805 = 20975273200
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
782 : 1, 2, 17, 23, 34, 46, 391, 782
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,782,196,805, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
782:2x 17x 23
196:2x 2x 7x 7
805:5x 7x 23
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 7x 17x 23 = 54740
Therefore, the value for common factors is 54740.
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 = 20975273200/(1x54740)
LCM = 20975273200/54740
LCM = 383180
Thus, we can understand that the LCM of 170,782,196,805 is 383180.
