Given numbers are 279,711,921,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,711,921,747 is 561626721.
Find LCM of 279,711,921,747 with Prime Factorization
| 3 | 279, 711, 921, 747 |
| 3 | 93, 237, 307, 249 |
| 31, 79, 307, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 31 x 79 x 307 x 83 = 561626721
Therefore, the lowest common multiple of 279,711,921,747 is 561626721.
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.
279 x 711 x 921 x 747 = 136475293203
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.
279 : 1, 3, 9, 31, 93, 279
711 : 1, 3, 9, 79, 237, 711
921 : 1, 3, 307, 921
747 : 1, 3, 9, 83, 249, 747
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,711,921,747, is 3.
Now, the common factors can be found like this.
279:3x 3x 31
711:3x 3x 79
921:3x 307
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 136475293203/(3x81)
LCM = 136475293203/243
LCM = 561626721
Thus, we can understand that the LCM of 279,711,921,747 is 561626721.
