The LCM of 238,686,589,939,380 is 64499140020.
Find LCM of 238,686,589,939,380 with Prime Factorization
| 2 | 238, 686, 589, 939, 380 |
| 7 | 119, 343, 589, 939, 190 |
| 19 | 17, 49, 589, 939, 190 |
| 17, 49, 31, 939, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 17 x 49 x 31 x 939 x 10 = 64499140020
Therefore, the lowest common multiple of 238,686,589,939,380 is 64499140020.
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.
238 x 686 x 589 x 939 x 380 = 34313542490640
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
686 : 1, 2, 7, 14, 49, 98, 343, 686
589 : 1, 19, 31, 589
939 : 1, 3, 313, 939
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,686,589,939,380, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
686:2x 7x 7x 7
589:19x 31
939:3x 313
380:2x 2x 5x 19
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 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 34313542490640/(1x532)
LCM = 34313542490640/532
LCM = 64499140020
Thus, we can understand that the LCM of 238,686,589,939,380 is 64499140020.
