So the greatest common factor 20,738,275 is 1.
Lets's calculate LCM of 345,269,397
Given numbers has no common factors except 1. So, there LCM is their product i.e 36843585
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/36843585
Therefore, the GCF of Fractions 20/345,738/269,275/397 is 1/36843585
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 345,269,397 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(345,269,397) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(345,269,397) x common factors =1 x 1 = 1
LCM(345,269,397) = ( 345 × 269 × 397 ) / 1
LCM(345,269,397) = 36843585 / 1
LCM(345,269,397) = 36843585
