Lets's calculate LCM of 415,977
Given numbers has no common factors except 1. So, there LCM is their product i.e 405455
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/405455
Therefore, the GCF of Fractions 824/415,657/977 is 1/405455
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 415,977 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(415,977) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(415,977) x common factors =1 x 1 = 1
LCM(415,977) = ( 415 × 977 ) / 1
LCM(415,977) = 405455 / 1
LCM(415,977) = 405455
