Lets's calculate LCM of 797,1240
Given numbers has no common factors except 1. So, there LCM is their product i.e 988280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/988280
Therefore, the GCF of Fractions 2686/797,7972/1240 is 2/988280
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 797,1240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(797,1240) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(797,1240) x common factors =1 x 1 = 1
LCM(797,1240) = ( 797 × 1240 ) / 1
LCM(797,1240) = 988280 / 1
LCM(797,1240) = 988280
