So the greatest common factor 8240,7772 is 4.
Lets's calculate LCM of 86,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 67166
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/67166
Therefore, the GCF of Fractions 8240/86,7772/781 is 4/67166
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 86,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(86,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(86,781) x common factors =1 x 1 = 1
LCM(86,781) = ( 86 × 781 ) / 1
LCM(86,781) = 67166 / 1
LCM(86,781) = 67166
