Given numbers are 343,261,394,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,261,394,203 is 35272062.
Find LCM of 343,261,394,203 with Prime Factorization
| 7 | 343, 261, 394, 203 |
| 29 | 49, 261, 394, 29 |
| 49, 9, 394, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 49 x 9 x 394 x 1 = 35272062
Therefore, the lowest common multiple of 343,261,394,203 is 35272062.
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.
343 x 261 x 394 x 203 = 7160228586
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.
343 : 1, 7, 49, 343
261 : 1, 3, 9, 29, 87, 261
394 : 1, 2, 197, 394
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,261,394,203, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
261:3x 3x 29
394:2x 197
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 29 = 203
Therefore, the value for common factors is 203.
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 = 7160228586/(1x203)
LCM = 7160228586/203
LCM = 35272062
Thus, we can understand that the LCM of 343,261,394,203 is 35272062.
