Lets's calculate LCM of 276,166
2 | 276, 166 |
138, 83 |
∴ So the LCM of the given numbers is 2 x 138 x 83 = 22908
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/22908
Therefore, the GCF of Fractions 644/276,4538/166 is 2/22908
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 276,166 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(276,166) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(276,166) x common factors =2 x 1 = 2
LCM(276,166) = ( 276 × 166 ) / 2
LCM(276,166) = 45816 / 2
LCM(276,166) = 22908
