Find LCM of 392,800,405,804,361 with Prime Factorization
| 2 | 392, 800, 405, 804, 361 |
| 2 | 196, 400, 405, 402, 361 |
| 2 | 98, 200, 405, 201, 361 |
| 3 | 49, 100, 405, 201, 361 |
| 5 | 49, 100, 135, 67, 361 |
| 49, 20, 27, 67, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 49 x 20 x 27 x 67 x 361 = 76798562400
Therefore, the lowest common multiple of 392,800,405,804,361 is 76798562400.
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.
392 x 800 x 405 x 804 x 361 = 36863309952000
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,800,405,804,361, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
800:2x 2x 2x 2x 2x 5x 5
405:3x 3x 3x 3x 5
804:2x 2x 3x 67
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 36863309952000/(1x480)
LCM = 36863309952000/480
LCM = 76798562400
Thus, we can understand that the LCM of 392,800,405,804,361 is 76798562400.
