So the greatest common factor 49,680,398 is 1.
Lets's calculate LCM of 97,29,769
Given numbers has no common factors except 1. So, there LCM is their product i.e 2163197
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2163197
Therefore, the GCF of Fractions 49/97,680/29,398/769 is 1/2163197
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 97,29,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,29,769) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(97,29,769) x common factors =1 x 1 = 1
LCM(97,29,769) = ( 97 × 29 × 769 ) / 1
LCM(97,29,769) = 2163197 / 1
LCM(97,29,769) = 2163197
