Given numbers are 813,687,836,807,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,687,836,807,654 is 4563636903012.
Find LCM of 813,687,836,807,654 with Prime Factorization
| 2 | 813, 687, 836, 807, 654 |
| 3 | 813, 687, 418, 807, 327 |
| 271, 229, 418, 269, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 271 x 229 x 418 x 269 x 109 = 4563636903012
Therefore, the lowest common multiple of 813,687,836,807,654 is 4563636903012.
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 687 x 836 x 807 x 654 = 246436392762648
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
687 : 1, 3, 229, 687
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
807 : 1, 3, 269, 807
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,687,836,807,654, is 1.
Now, the common factors can be found like this.
813:3x 271
687:3x 229
836:2x 2x 11x 19
807:3x 269
654:2x 3x 109
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 3 = 54
Therefore, the value for common factors is 54.
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 = 246436392762648/(1x54)
LCM = 246436392762648/54
LCM = 4563636903012
Thus, we can understand that the LCM of 813,687,836,807,654 is 4563636903012.
