Given numbers are 217,904,683,816,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,904,683,816,947 is 12941929173936.
Find LCM of 217,904,683,816,947 with Prime Factorization
| 2 | 217, 904, 683, 816, 947 |
| 2 | 217, 452, 683, 408, 947 |
| 2 | 217, 226, 683, 204, 947 |
| 217, 113, 683, 102, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 217 x 113 x 683 x 102 x 947 = 12941929173936
Therefore, the lowest common multiple of 217,904,683,816,947 is 12941929173936.
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.
217 x 904 x 683 x 816 x 947 = 103535433391488
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.
217 : 1, 7, 31, 217
904 : 1, 2, 4, 8, 113, 226, 452, 904
683 : 1, 683
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,904,683,816,947, is 1.
Now, the common factors can be found like this.
217:7x 31
904:2x 2x 2x 113
683:683
816:2x 2x 2x 2x 3x 17
947:947
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 2 = 8
Therefore, the value for common factors is 8.
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 = 103535433391488/(1x8)
LCM = 103535433391488/8
LCM = 12941929173936
Thus, we can understand that the LCM of 217,904,683,816,947 is 12941929173936.
