Lets's calculate LCM of 577,761
Given numbers has no common factors except 1. So, there LCM is their product i.e 439097
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/439097
Therefore, the GCF of Fractions 775/577,663/761 is 1/439097
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 577,761 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(577,761) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(577,761) x common factors =1 x 1 = 1
LCM(577,761) = ( 577 × 761 ) / 1
LCM(577,761) = 439097 / 1
LCM(577,761) = 439097
