Given numbers are 723,789,711,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,789,711,397 is 17890929261.
Find LCM of 723,789,711,397 with Prime Factorization
| 3 | 723, 789, 711, 397 |
| 241, 263, 237, 397 |
Multiply the prime numbers at the bottom and the left side.
3 x 241 x 263 x 237 x 397 = 17890929261
Therefore, the lowest common multiple of 723,789,711,397 is 17890929261.
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 789 x 711 x 397 = 161018363349
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
789 : 1, 3, 263, 789
711 : 1, 3, 9, 79, 237, 711
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,789,711,397, is 1.
Now, the common factors can be found like this.
723:3x 241
789:3x 263
711:3x 3x 79
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 161018363349/(1x9)
LCM = 161018363349/9
LCM = 17890929261
Thus, we can understand that the LCM of 723,789,711,397 is 17890929261.
