Given numbers are 723,261,209,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,261,209,431 is 5666059179.
Find LCM of 723,261,209,431 with Prime Factorization
| 3 | 723, 261, 209, 431 |
| 241, 87, 209, 431 |
Multiply the prime numbers at the bottom and the left side.
3 x 241 x 87 x 209 x 431 = 5666059179
Therefore, the lowest common multiple of 723,261,209,431 is 5666059179.
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.
723 x 261 x 209 x 431 = 16998177537
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.
723 : 1, 3, 241, 723
261 : 1, 3, 9, 29, 87, 261
209 : 1, 11, 19, 209
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,261,209,431, is 1.
Now, the common factors can be found like this.
723:3x 241
261:3x 3x 29
209:11x 19
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 16998177537/(1x3)
LCM = 16998177537/3
LCM = 5666059179
Thus, we can understand that the LCM of 723,261,209,431 is 5666059179.
