So the greatest common factor 74,40,458 is 2.
Lets's calculate LCM of 669,670,989
Given numbers has no common factors except 1. So, there LCM is their product i.e 443299470
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/443299470
Therefore, the GCF of Fractions 74/669,40/670,458/989 is 2/443299470
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 669,670,989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(669,670,989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(669,670,989) x common factors =1 x 1 = 1
LCM(669,670,989) = ( 669 × 670 × 989 ) / 1
LCM(669,670,989) = 443299470 / 1
LCM(669,670,989) = 443299470
