So the greatest common factor 772,492 is 4.
Lets's calculate LCM of 836,505
Given numbers has no common factors except 1. So, there LCM is their product i.e 422180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/422180
Therefore, the GCF of Fractions 772/836,492/505 is 4/422180
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 836,505 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(836,505) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(836,505) x common factors =1 x 1 = 1
LCM(836,505) = ( 836 × 505 ) / 1
LCM(836,505) = 422180 / 1
LCM(836,505) = 422180
