Find LCM of 789,749,750,847,847 with Prime Factorization
| 3 | 789, 749, 750, 847, 847 |
| 7 | 263, 749, 250, 847, 847 |
| 11 | 263, 107, 250, 121, 121 |
| 11 | 263, 107, 250, 11, 11 |
| 263, 107, 250, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 11 x 263 x 107 x 250 x 1 x 1 = 17876570250
Therefore, the lowest common multiple of 789,749,750,847,847 is 17876570250.
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 749 x 750 x 847 x 847 = 317970555036750
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
749 : 1, 7, 107, 749
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
847 : 1, 7, 11, 77, 121, 847
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,749,750,847,847, is 1.
Now, the common factors can be found like this.
789:3x 263
749:7x 107
750:2x 3x 5x 5x 5
847:7x 11x 11
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11x 11 = 17787
Therefore, the value for common factors is 17787.
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 = 317970555036750/(1x17787)
LCM = 317970555036750/17787
LCM = 17876570250
Thus, we can understand that the LCM of 789,749,750,847,847 is 17876570250.
