The HCF of 287,205 is 41.
Lets's calculate GCF of 287,205
| 41 | 287, 205 |
| 7, 5 |
∴ So the GCF of the given numbers is 41 = 41
Now, list down the factors of 287
:1,7,41,287
Now, list down the factors of 205
:1,5,41,205
Greatest Common Factor
We found the factors 287,205 . The biggest common factor number is the GCF number.
So the greatest common factor 287,205 is 41.
Lets's calculate LCM of 827,494
Given numbers has no common factors except 1. So, there LCM is their product i.e 408538
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 41/408538
Therefore, the GCF of Fractions 287/827,205/494 is 41/408538
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 827,494 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(827,494) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(827,494) x common factors =1 x 1 = 1
LCM(827,494) = ( 827 × 494 ) / 1
LCM(827,494) = 408538 / 1
LCM(827,494) = 408538
