Lets's calculate LCM of 11,70,57
Given numbers has no common factors except 1. So, there LCM is their product i.e 43890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/43890
Therefore, the GCF of Fractions 53/11,64/70,403/57 is 1/43890
Least Common Multiple of 11,70,57 with GCF Formula
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 11,70,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,70,57) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(11,70,57) x common factors =1 x 1 = 1
LCM(11,70,57) = ( 11 × 70 × 57 ) / 1
LCM(11,70,57) = 43890 / 1
LCM(11,70,57) = 43890
