Lets's calculate LCM of 257,824
Given numbers has no common factors except 1. So, there LCM is their product i.e 211768
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/211768
Therefore, the GCF of Fractions 1720/257,7342/824 is 2/211768
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 257,824 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(257,824) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(257,824) x common factors =1 x 1 = 1
LCM(257,824) = ( 257 × 824 ) / 1
LCM(257,824) = 211768 / 1
LCM(257,824) = 211768
