Given numbers are 385,232,343,998,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,232,343,998,678 is 740363565480.
Find LCM of 385,232,343,998,678 with Prime Factorization
| 2 | 385, 232, 343, 998, 678 |
| 7 | 385, 116, 343, 499, 339 |
| 55, 116, 49, 499, 339 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 55 x 116 x 49 x 499 x 339 = 740363565480
Therefore, the lowest common multiple of 385,232,343,998,678 is 740363565480.
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.
385 x 232 x 343 x 998 x 678 = 20730179833440
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
232 : 1, 2, 4, 8, 29, 58, 116, 232
343 : 1, 7, 49, 343
998 : 1, 2, 499, 998
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,232,343,998,678, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
232:2x 2x 2x 29
343:7x 7x 7
998:2x 499
678:2x 3x 113
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 7 = 28
Therefore, the value for common factors is 28.
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 = 20730179833440/(1x28)
LCM = 20730179833440/28
LCM = 740363565480
Thus, we can understand that the LCM of 385,232,343,998,678 is 740363565480.
