Lets's calculate LCM of 490,443
Given numbers has no common factors except 1. So, there LCM is their product i.e 217070
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/217070
Therefore, the GCF of Fractions 694/490,988/443 is 2/217070
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 490,443 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(490,443) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(490,443) x common factors =1 x 1 = 1
LCM(490,443) = ( 490 × 443 ) / 1
LCM(490,443) = 217070 / 1
LCM(490,443) = 217070
