The LCM of 813,448,504,802 is 438161472.
Find LCM of 813,448,504,802 with Prime Factorization
| 2 | 813, 448, 504, 802 |
| 2 | 813, 224, 252, 401 |
| 2 | 813, 112, 126, 401 |
| 3 | 813, 56, 63, 401 |
| 7 | 271, 56, 21, 401 |
| 271, 8, 3, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 271 x 8 x 3 x 401 = 438161472
Therefore, the lowest common multiple of 813,448,504,802 is 438161472.
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.
813 x 448 x 504 x 802 = 147222254592
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.
813 : 1, 3, 271, 813
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,448,504,802, is 1.
Now, the common factors can be found like this.
813:3x 271
448:2x 2x 2x 2x 2x 2x 7
504:2x 2x 2x 3x 3x 7
802:2x 401
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 147222254592/(1x336)
LCM = 147222254592/336
LCM = 438161472
Thus, we can understand that the LCM of 813,448,504,802 is 438161472.
