Lets's calculate LCM of 287,974
Given numbers has no common factors except 1. So, there LCM is their product i.e 279538
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/279538
Therefore, the GCF of Fractions 422/287,306/974 is 2/279538
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 287,974 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(287,974) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(287,974) x common factors =1 x 1 = 1
LCM(287,974) = ( 287 × 974 ) / 1
LCM(287,974) = 279538 / 1
LCM(287,974) = 279538
