So the greatest common factor 171,280 is 1.
Lets's calculate LCM of 69,749
Given numbers has no common factors except 1. So, there LCM is their product i.e 51681
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/51681
Therefore, the GCF of Fractions 171/69,280/749 is 1/51681
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 69,749 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,749) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(69,749) x common factors =1 x 1 = 1
LCM(69,749) = ( 69 × 749 ) / 1
LCM(69,749) = 51681 / 1
LCM(69,749) = 51681
