Find LCM of 765,318,954,388 with Prime Factorization
| 2 | 765, 318, 954, 388 |
| 3 | 765, 159, 477, 194 |
| 3 | 255, 53, 159, 194 |
| 53 | 85, 53, 53, 194 |
| 85, 1, 1, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 53 x 85 x 1 x 1 x 194 = 15731460
Therefore, the lowest common multiple of 765,318,954,388 is 15731460.
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.
765 x 318 x 954 x 388 = 90046877040
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
318 : 1, 2, 3, 6, 53, 106, 159, 318
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,318,954,388, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
318:2x 3x 53
954:2x 3x 3x 53
388:2x 2x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 53 = 5724
Therefore, the value for common factors is 5724.
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 = 90046877040/(1x5724)
LCM = 90046877040/5724
LCM = 15731460
Thus, we can understand that the LCM of 765,318,954,388 is 15731460.
