Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/693755
Therefore, the GCF of Fractions 86/445,3954/7795 is 2/693755
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 445,7795 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(445,7795) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(445,7795) x common factors =5 x 1 = 5
LCM(445,7795) = ( 445 × 7795 ) / 5
LCM(445,7795) = 3468775 / 5
LCM(445,7795) = 693755
