Find LCM of 198,782,853,666,238 with Prime Factorization
| 2 | 198, 782, 853, 666, 238 |
| 3 | 99, 391, 853, 333, 119 |
| 3 | 33, 391, 853, 111, 119 |
| 17 | 11, 391, 853, 37, 119 |
| 11, 23, 853, 37, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 11 x 23 x 853 x 37 x 7 = 17103726486
Therefore, the lowest common multiple of 198,782,853,666,238 is 17103726486.
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.
198 x 782 x 853 x 666 x 238 = 20934961218864
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
782 : 1, 2, 17, 23, 34, 46, 391, 782
853 : 1, 853
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,782,853,666,238, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
782:2x 17x 23
853:853
666:2x 3x 3x 37
238:2x 7x 17
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 17 = 1224
Therefore, the value for common factors is 1224.
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 = 20934961218864/(1x1224)
LCM = 20934961218864/1224
LCM = 17103726486
Thus, we can understand that the LCM of 198,782,853,666,238 is 17103726486.
