Given numbers are 279,285,789,589
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,285,789,589 is 6970815.
Find LCM of 279,285,789,589 with Prime Factorization
| 3 | 279, 285, 789, 589 |
| 19 | 93, 95, 263, 589 |
| 31 | 93, 5, 263, 31 |
| 3, 5, 263, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 31 x 3 x 5 x 263 x 1 = 6970815
Therefore, the lowest common multiple of 279,285,789,589 is 6970815.
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 285 x 789 x 589 = 36952290315
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
285 : 1, 3, 5, 15, 19, 57, 95, 285
789 : 1, 3, 263, 789
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,285,789,589, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
285:3x 5x 19
789:3x 263
589:19x 31
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 19x 31 = 5301
Therefore, the value for common factors is 5301.
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 = 36952290315/(1x5301)
LCM = 36952290315/5301
LCM = 6970815
Thus, we can understand that the LCM of 279,285,789,589 is 6970815.
