Find LCM of 126,525,990,729,493 with Prime Factorization
| 2 | 126, 525, 990, 729, 493 |
| 3 | 63, 525, 495, 729, 493 |
| 3 | 21, 175, 165, 243, 493 |
| 5 | 7, 175, 55, 81, 493 |
| 7 | 7, 35, 11, 81, 493 |
| 1, 5, 11, 81, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 1 x 5 x 11 x 81 x 493 = 1383678450
Therefore, the lowest common multiple of 126,525,990,729,493 is 1383678450.
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.
126 x 525 x 990 x 729 x 493 = 23536370434500
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
729 : 1, 3, 9, 27, 81, 243, 729
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,525,990,729,493, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
525:3x 5x 5x 7
990:2x 3x 3x 5x 11
729:3x 3x 3x 3x 3x 3
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 5x 7 = 17010
Therefore, the value for common factors is 17010.
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 = 23536370434500/(1x17010)
LCM = 23536370434500/17010
LCM = 1383678450
Thus, we can understand that the LCM of 126,525,990,729,493 is 1383678450.
