The LCM of 255,397,865,867 is 297732135.
Find LCM of 255,397,865,867 with Prime Factorization
| 3 | 255, 397, 865, 867 |
| 5 | 85, 397, 865, 289 |
| 17 | 17, 397, 173, 289 |
| 1, 397, 173, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 1 x 397 x 173 x 17 = 297732135
Therefore, the lowest common multiple of 255,397,865,867 is 297732135.
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.
255 x 397 x 865 x 867 = 75921694425
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
397 : 1, 397
865 : 1, 5, 173, 865
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,397,865,867, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
397:397
865:5x 173
867:3x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 17 = 255
Therefore, the value for common factors is 255.
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 = 75921694425/(1x255)
LCM = 75921694425/255
LCM = 297732135
Thus, we can understand that the LCM of 255,397,865,867 is 297732135.
