Lets's calculate LCM of 428,9898
2 | 428, 9898 |
214, 4949 |
∴ So the LCM of the given numbers is 2 x 214 x 4949 = 2118172
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2118172
Therefore, the GCF of Fractions 1872/428,1894/9898 is 2/2118172
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 428,9898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(428,9898) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(428,9898) x common factors =2 x 1 = 2
LCM(428,9898) = ( 428 × 9898 ) / 2
LCM(428,9898) = 4236344 / 2
LCM(428,9898) = 2118172
