So the greatest common factor 637,315 is 7.
Lets's calculate LCM of 401,725
Given numbers has no common factors except 1. So, there LCM is their product i.e 290725
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/290725
Therefore, the GCF of Fractions 637/401,315/725 is 7/290725
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 401,725 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(401,725) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(401,725) x common factors =1 x 1 = 1
LCM(401,725) = ( 401 × 725 ) / 1
LCM(401,725) = 290725 / 1
LCM(401,725) = 290725
