So the greatest common factor 39,208,813 is 1.
Lets's calculate LCM of 69,26,917
Given numbers has no common factors except 1. So, there LCM is their product i.e 1645098
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1645098
Therefore, the GCF of Fractions 39/69,208/26,813/917 is 1/1645098
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 69,26,917 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,26,917) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(69,26,917) x common factors =1 x 1 = 1
LCM(69,26,917) = ( 69 × 26 × 917 ) / 1
LCM(69,26,917) = 1645098 / 1
LCM(69,26,917) = 1645098
