Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9870
Therefore, the GCF of Fractions 41/47,18/21,62/70 is 1/9870
Least Common Multiple of 47,21,70 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 47,21,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,21,70) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(47,21,70) x common factors =1 x 7 = 7
LCM(47,21,70) = ( 47 × 21 × 70 ) / 7
LCM(47,21,70) = 69090 / 7
LCM(47,21,70) = 9870
