So the greatest common factor 6840,6045 is 15.
Lets's calculate LCM of 291,440
Given numbers has no common factors except 1. So, there LCM is their product i.e 128040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/128040
Therefore, the GCF of Fractions 6840/291,6045/440 is 15/128040
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 291,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(291,440) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(291,440) x common factors =1 x 1 = 1
LCM(291,440) = ( 291 × 440 ) / 1
LCM(291,440) = 128040 / 1
LCM(291,440) = 128040
