Find LCM of 789,212,256,656,469 with Prime Factorization
| 2 | 789, 212, 256, 656, 469 |
| 2 | 789, 106, 128, 328, 469 |
| 2 | 789, 53, 64, 164, 469 |
| 2 | 789, 53, 32, 82, 469 |
| 789, 53, 16, 41, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 789 x 53 x 16 x 41 x 469 = 205849367808
Therefore, the lowest common multiple of 789,212,256,656,469 is 205849367808.
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.
789 x 212 x 256 x 656 x 469 = 13174359539712
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.
789 : 1, 3, 263, 789
212 : 1, 2, 4, 53, 106, 212
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,212,256,656,469, is 1.
Now, the common factors can be found like this.
789:3x 263
212:2x 2x 53
256:2x 2x 2x 2x 2x 2x 2x 2
656:2x 2x 2x 2x 41
469:7x 67
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 2x 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 13174359539712/(1x64)
LCM = 13174359539712/64
LCM = 205849367808
Thus, we can understand that the LCM of 789,212,256,656,469 is 205849367808.
