So the greatest common factor 378,665 is 7.
Lets's calculate LCM of 841,260
Given numbers has no common factors except 1. So, there LCM is their product i.e 218660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/218660
Therefore, the GCF of Fractions 378/841,665/260 is 7/218660
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 841,260 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(841,260) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(841,260) x common factors =1 x 1 = 1
LCM(841,260) = ( 841 × 260 ) / 1
LCM(841,260) = 218660 / 1
LCM(841,260) = 218660
