So the greatest common factor 32,968,640 is 8.
Lets's calculate LCM of 61,64,769
Given numbers has no common factors except 1. So, there LCM is their product i.e 3002176
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/3002176
Therefore, the GCF of Fractions 32/61,968/64,640/769 is 8/3002176
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 61,64,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,64,769) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,64,769) x common factors =1 x 1 = 1
LCM(61,64,769) = ( 61 × 64 × 769 ) / 1
LCM(61,64,769) = 3002176 / 1
LCM(61,64,769) = 3002176
