Find LCM of 940,361,486,405 with Prime Factorization
| 2 | 940, 361, 486, 405 |
| 3 | 470, 361, 243, 405 |
| 3 | 470, 361, 81, 135 |
| 3 | 470, 361, 27, 45 |
| 3 | 470, 361, 9, 15 |
| 5 | 470, 361, 3, 5 |
| 94, 361, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 94 x 361 x 3 x 1 = 82459620
Therefore, the lowest common multiple of 940,361,486,405 is 82459620.
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.
940 x 361 x 486 x 405 = 66792292200
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
361 : 1, 19, 361
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,361,486,405, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
361:19x 19
486:2x 3x 3x 3x 3x 3
405:3x 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 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 = 66792292200/(1x810)
LCM = 66792292200/810
LCM = 82459620
Thus, we can understand that the LCM of 940,361,486,405 is 82459620.
