Lets's calculate LCM of 173,890
Given numbers has no common factors except 1. So, there LCM is their product i.e 153970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/153970
Therefore, the GCF of Fractions 2542/173,3990/890 is 2/153970
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 173,890 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(173,890) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(173,890) x common factors =1 x 1 = 1
LCM(173,890) = ( 173 × 890 ) / 1
LCM(173,890) = 153970 / 1
LCM(173,890) = 153970
