Greatest Common Factor
We found the factors 161,118 . The biggest common factor number is the GCF number.
So the greatest common factor 161,118 is 1.
Lets's calculate LCM of 196,236
2 | 196, 236 |
2 | 98, 118 |
49, 59 |
∴ So the LCM of the given numbers is 2 x 2 x 49 x 59 = 11564
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11564
Therefore, the GCF of Fractions 161/196,118/236 is 1/11564
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 196,236 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(196,236) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(196,236) x common factors =4 x 1 = 4
LCM(196,236) = ( 196 × 236 ) / 4
LCM(196,236) = 46256 / 4
LCM(196,236) = 11564
