Lets's calculate LCM of 244,168
2 | 244, 168 |
2 | 122, 84 |
61, 42 |
∴ So the LCM of the given numbers is 2 x 2 x 61 x 42 = 10248
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10248
Therefore, the GCF of Fractions 494/244,138/168 is 2/10248
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 244,168 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(244,168) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(244,168) x common factors =4 x 1 = 4
LCM(244,168) = ( 244 × 168 ) / 4
LCM(244,168) = 40992 / 4
LCM(244,168) = 10248
