Lets's calculate LCM of 625,238
Given numbers has no common factors except 1. So, there LCM is their product i.e 148750
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/148750
Therefore, the GCF of Fractions 225/625,978/238 is 3/148750
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 625,238 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(625,238) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(625,238) x common factors =1 x 1 = 1
LCM(625,238) = ( 625 × 238 ) / 1
LCM(625,238) = 148750 / 1
LCM(625,238) = 148750
