Find LCM of 945,514,810,249 with Prime Factorization
| 2 | 945, 514, 810, 249 |
| 3 | 945, 257, 405, 249 |
| 3 | 315, 257, 135, 83 |
| 3 | 105, 257, 45, 83 |
| 5 | 35, 257, 15, 83 |
| 7, 257, 3, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 257 x 3 x 83 = 120946770
Therefore, the lowest common multiple of 945,514,810,249 is 120946770.
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.
945 x 514 x 810 x 249 = 97966883700
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
514 : 1, 2, 257, 514
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,514,810,249, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
514:2x 257
810:2x 3x 3x 3x 3x 5
249:3x 83
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 5 = 810
Therefore, the value for common factors is 810.
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 = 97966883700/(1x810)
LCM = 97966883700/810
LCM = 120946770
Thus, we can understand that the LCM of 945,514,810,249 is 120946770.
