Given numbers are 208,636,159,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,636,159,831 is 9160944.
Find LCM of 208,636,159,831 with Prime Factorization
| 2 | 208, 636, 159, 831 |
| 2 | 104, 318, 159, 831 |
| 3 | 52, 159, 159, 831 |
| 53 | 52, 53, 53, 277 |
| 52, 1, 1, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 52 x 1 x 1 x 277 = 9160944
Therefore, the lowest common multiple of 208,636,159,831 is 9160944.
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.
208 x 636 x 159 x 831 = 17479081152
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
159 : 1, 3, 53, 159
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,636,159,831, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
636:2x 2x 3x 53
159:3x 53
831:3x 277
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 3x 3x 53 = 1908
Therefore, the value for common factors is 1908.
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 = 17479081152/(1x1908)
LCM = 17479081152/1908
LCM = 9160944
Thus, we can understand that the LCM of 208,636,159,831 is 9160944.
