Given numbers are 208,143,797,644,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,143,797,644,285 is 83672949360.
Find LCM of 208,143,797,644,285 with Prime Factorization
| 2 | 208, 143, 797, 644, 285 |
| 2 | 104, 143, 797, 322, 285 |
| 13 | 52, 143, 797, 161, 285 |
| 4, 11, 797, 161, 285 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 4 x 11 x 797 x 161 x 285 = 83672949360
Therefore, the lowest common multiple of 208,143,797,644,285 is 83672949360.
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 143 x 797 x 644 x 285 = 4350993366720
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
143 : 1, 11, 13, 143
797 : 1, 797
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,143,797,644,285, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
143:11x 13
797:797
644:2x 2x 7x 23
285:3x 5x 19
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 13 = 52
Therefore, the value for common factors is 52.
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 = 4350993366720/(1x52)
LCM = 4350993366720/52
LCM = 83672949360
Thus, we can understand that the LCM of 208,143,797,644,285 is 83672949360.
