We found the factors 765,3280 . The biggest common factor number is the GCF number.
So the greatest common factor 765,3280 is 5.
Lets's calculate LCM of 81,511
Given numbers has no common factors except 1. So, there LCM is their product i.e 41391
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/41391
Therefore, the GCF of Fractions 765/81,3280/511 is 5/41391
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 81,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,511) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,511) x common factors =1 x 1 = 1
LCM(81,511) = ( 81 × 511 ) / 1
LCM(81,511) = 41391 / 1
LCM(81,511) = 41391
