Given numbers are 256,206,504,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,206,504,686 is 81398016.
Find LCM of 256,206,504,686 with Prime Factorization
| 2 | 256, 206, 504, 686 |
| 2 | 128, 103, 252, 343 |
| 2 | 64, 103, 126, 343 |
| 7 | 32, 103, 63, 343 |
| 32, 103, 9, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 32 x 103 x 9 x 49 = 81398016
Therefore, the lowest common multiple of 256,206,504,686 is 81398016.
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.
256 x 206 x 504 x 686 = 18233155584
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
206 : 1, 2, 103, 206
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,206,504,686, is 2.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
206:2x 103
504:2x 2x 2x 3x 3x 7
686:2x 7x 7x 7
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 7 = 112
Therefore, the value for common factors is 112.
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 = 18233155584/(2x112)
LCM = 18233155584/224
LCM = 81398016
Thus, we can understand that the LCM of 256,206,504,686 is 81398016.
