So the greatest common factor 13,90,697 is 1.
Lets's calculate LCM of 197,774,605
Given numbers has no common factors except 1. So, there LCM is their product i.e 92249190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/92249190
Therefore, the GCF of Fractions 13/197,90/774,697/605 is 1/92249190
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 197,774,605 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(197,774,605) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(197,774,605) x common factors =1 x 1 = 1
LCM(197,774,605) = ( 197 × 774 × 605 ) / 1
LCM(197,774,605) = 92249190 / 1
LCM(197,774,605) = 92249190
