Given numbers are 816,663,211,811,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,663,211,811,654 is 197862420912.
Find LCM of 816,663,211,811,654 with Prime Factorization
| 2 | 816, 663, 211, 811, 654 |
| 3 | 408, 663, 211, 811, 327 |
| 17 | 136, 221, 211, 811, 109 |
| 8, 13, 211, 811, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 8 x 13 x 211 x 811 x 109 = 197862420912
Therefore, the lowest common multiple of 816,663,211,811,654 is 197862420912.
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.
816 x 663 x 211 x 811 x 654 = 60545900799072
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
663 : 1, 3, 13, 17, 39, 51, 221, 663
211 : 1, 211
811 : 1, 811
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 816,663,211,811,654, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
663:3x 13x 17
211:211
811:811
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 17 = 306
Therefore, the value for common factors is 306.
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 = 60545900799072/(1x306)
LCM = 60545900799072/306
LCM = 197862420912
Thus, we can understand that the LCM of 816,663,211,811,654 is 197862420912.
