So the greatest common factor 447,972 is 3.
Lets's calculate LCM of 835,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 101035
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/101035
Therefore, the GCF of Fractions 447/835,972/121 is 3/101035
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 835,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(835,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(835,121) x common factors =1 x 1 = 1
LCM(835,121) = ( 835 × 121 ) / 1
LCM(835,121) = 101035 / 1
LCM(835,121) = 101035
