Lets's calculate LCM of 398,251
Given numbers has no common factors except 1. So, there LCM is their product i.e 99898
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/99898
Therefore, the GCF of Fractions 748/398,913/251 is 11/99898
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 398,251 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(398,251) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(398,251) x common factors =1 x 1 = 1
LCM(398,251) = ( 398 × 251 ) / 1
LCM(398,251) = 99898 / 1
LCM(398,251) = 99898
