The factors of 243 are 1, 3, 9, 27, 81, 243
The HCF of 417,243 is 3.
Lets's calculate GCF of 417,243
3 | 417, 243 |
139, 81 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 417
:1,3,139,417
Now, list down the factors of 243
:1,3,9,27,81,243
Greatest Common Factor
We found the factors 417,243 . The biggest common factor number is the GCF number.
So the greatest common factor 417,243 is 3.
Lets's calculate LCM of 16,770
2 | 16, 770 |
8, 385 |
∴ So the LCM of the given numbers is 2 x 8 x 385 = 6160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/6160
Therefore, the GCF of Fractions 417/16,243/770 is 3/6160
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 16,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,770) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(16,770) x common factors =2 x 1 = 2
LCM(16,770) = ( 16 × 770 ) / 2
LCM(16,770) = 12320 / 2
LCM(16,770) = 6160
