Find LCM of 243,422,825,810 with Prime Factorization
| 2 | 243, 422, 825, 810 |
| 3 | 243, 211, 825, 405 |
| 3 | 81, 211, 275, 135 |
| 3 | 27, 211, 275, 45 |
| 3 | 9, 211, 275, 15 |
| 5 | 3, 211, 275, 5 |
| 3, 211, 55, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 3 x 211 x 55 x 1 = 28200150
Therefore, the lowest common multiple of 243,422,825,810 is 28200150.
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.
243 x 422 x 825 x 810 = 68526364500
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.
243 : 1, 3, 9, 27, 81, 243
422 : 1, 2, 211, 422
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,422,825,810, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
422:2x 211
825:3x 5x 5x 11
810:2x 3x 3x 3x 3x 5
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 5 = 2430
Therefore, the value for common factors is 2430.
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 = 68526364500/(1x2430)
LCM = 68526364500/2430
LCM = 28200150
Thus, we can understand that the LCM of 243,422,825,810 is 28200150.
