Given numbers are 865,725,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,725,789 is 98960325.
Find LCM of 865,725,789 with Prime Factorization
| 5 | 865, 725, 789 |
| 173, 145, 789 |
Multiply the prime numbers at the bottom and the left side.
5 x 173 x 145 x 789 = 98960325
Therefore, the lowest common multiple of 865,725,789 is 98960325.
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.
865 x 725 x 789 = 494801625
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.
865 : 1, 5, 173, 865
725 : 1, 5, 25, 29, 145, 725
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,725,789, is 1.
Now, the common factors can be found like this.
865:5x 173
725:5x 5x 29
789:3x 263
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 494801625/(1x5)
LCM = 494801625/5
LCM = 98960325
Thus, we can understand that the LCM of 865,725,789 is 98960325.
