Lets's calculate LCM of 570,349,587
Given numbers has no common factors except 1. So, there LCM is their product i.e 116771910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/116771910
Therefore, the GCF of Fractions 49/570,72/349,821/587 is 1/116771910
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 570,349,587 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(570,349,587) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(570,349,587) x common factors =1 x 1 = 1
LCM(570,349,587) = ( 570 × 349 × 587 ) / 1
LCM(570,349,587) = 116771910 / 1
LCM(570,349,587) = 116771910
